Published by Spencer Hill Press

Book Four in the Covenant Series

Fate isn't something to mess with and now, neither is Alex.

Alex has always feared two things: losing herself in the Awakening and being placed on the Elixir. But love has always been stronger than Fate, and Aiden St. Delphi is willing to make war on the gods—and Alex herself—to bring her back.

The gods have killed thousands and could destroy entire cities in their quest to stop Seth from taking Alex's power and becoming the all-powerful God Killer. But breaking Alex's connection to Seth isn't the only problem. There are a few pesky little loopholes in the whole an Apollyon can't be killed theory, and the only person who might know how to stop the destruction has been dead for centuries.

Finding their way past the barriers that guard the Underworld, searching for one soul among countless millions, and then somehow returning will be hard enough. Alex might be able to keep Seth from becoming the God Killer or she might become the God Killer herself.

Apollyon by Jennifer L Armentrout is the fourth book in the Covenant series, and starts up shortly after the novella Elixir. Alex has Awakened, and is connected to Seth in a way that makes her forget she is a separate person. She becomes incredibly dangerous, and cruel, but thankfully, she has Aiden, who refuses to give up on her, even if it's against the Gods wishes. In order to find out how to stop Seth from becoming the God Killer, Alex and Aiden are forced venture the unknown, the Underworld, looking amongst millions for the one person who has the answer they need.

I just knew how with the way Deity ended, Apollyon was going to be intense, and it delivered on its promise. Right away we start in on the action, with a very pissed off, angry Alex, who is obsessed with getting to "her Seth". It was really hard to read such a strong character be brought down like that, and frankly, made me feel icky. Which is the point, I suppose. I won't lie, I had a harder time getting through Apollyon than the past books. It wasn't just because of what Alex was going through, but the whole book has a darker theme, and my anxiety was constantly on the edge of tipping over. I just knew shit was about to get bad, and I was right. There were some things I just LOVED about this book, though. First of all, we get lots of Aiden and Alex moments. Their love for one another is intense and beautiful, and we get lots of those moments with them. I would usually try not to spoil you, but since its obvious that they do go to the Underworld in this book, its obvious who they would connect with - Caleb. I am always down for some Caleb and Alex scenes. Another thing I really enjoyed, was the new bonds Alex formed. With everything out on the table now, Marcus and Alex seem to be growing a uncle/niece bond, which Alex very much needs. She is even bonding with Lea some, even if they still trade insults. Its obvious they respect one another.

Actually, lets discuss Alex for a minute. That girl has done a lot of growing up since the first book. Is she still sometimes arrogant and a little clueless when it comes to others perceptions? Sure. But she has come a long way. A book ago, she would have never sat in a room, and acknowledged that she was the reason why her and Lea became rivals. It took a lot for her to admit that she didn't try to bond with her uncle, and she did test his patience ... frequently. She is still the temperamental and strong character we love, but she is learning that sometimes, she needs to be a little less reckless. Aiden has come a long way as well. He was always strong, but now that he is open with his feelings for Alex, now that he has her, his love for her is his biggest strength, and weakness. I think the thing I love the most, is in those quiet moments, when they aren't dealing with ... well, everything ... he is happy. We don't get a whole lot of Seth in Apollyon. What we do get, doesn't make me like his character. Like Alex though, I empathize. I think it's easy to see how Seth got sucked in, and I still have hope for him.

By the end of Apollyon, we are left with some answer, and a lot more questions. I honestly can't believe there is only one more book! I highly recommend this series.

Favorite Quotes

Aiden: "I know you're still in there, Alex. Underneath that connection, you are still you. The woman I love."

Aiden: "Nothing has changed."

Alex: "I have."

Aiden sighed

Aiden: "You haven't."

I opened my eyes

Alex: "Will you ever get bored with this? You have to, eventually."

Aiden: "Never."

Alex: "Because you won't give up on me, no matter what I tell you?"

Aiden: "Exactly."

Alex: "You're incredibly stubborn."

Aiden's lips tipped up in a half-smile

Aiden: "I used to say the same thing about you."

Caleb: "Oh, Alex, even I'm amazing by how inflated your ego has become. Gods, if I was fully corporeal, I'd so kick your ass right now."

Aiden: "I'm not going to leave you. I'll never do that."

Alex: "Give up."

His arms tightened around me

Aiden: "You should know by now I'm not going to give up on you. You're not that stupid."

Alex: "Can't say the same thing about you. You can't win."

Aiden: "You want to bet on that?"

Alex: "You can't have me. I'm not 0"

Aiden: "You're not his, Alex. You don't belong to anyone but yourself!"

Aiden: "What? Is this too fast? I should -"

Alex: "No. No, it's ... it's the marks of the Apollyon. They're kind of going their thing right now."

Aiden: "Should I be worried?"

Alex: "I think they like you."

Aiden's hand slid off my cheek, down my throat, to right below my chest. The marks slid toward his hand, as if drawn to him.

Aiden: "I saw them. When you Awakened, and when you went on the Elixir."

His brows drew tight as he smoothed his hand over my hip.

Aiden: "They were beautiful."

Alex: "Really?"

Aiden: "Yes. It was the most beautiful thing I'd ever seen."

Aiden: "Eiste panta mou ..."

You are my everything.

Solos: "I'm not going to bite, little one."

Alex: "Good. Because I bite back."

Solos: "That's what I hear."

Laadan: "Lea, dear, she has no reason to fake it. If she was connected to the FIrst, she wouldn't be sitting here."

Deacon: "And my brother wouldn't be cleaning up after us, right? Gods, we'd have to get a main then or something."

Aiden smacked the back of Deacon's head as he passed by

Aiden: "I feel the love."

Alex: "I can't believe Apollo hit me with a god bolt."

Marcus: "I can't believe Aiden punched him."

Alex: "What? You did not."

The half-grin spread until a dimple appeared in his left cheek.

Aiden: "I did."

Alex: "All those times you yelled at me for hitting people, and you hit a god?"

That half-grin turned into a full smile.

Aiden: "This was a different situation."

Laadan: "The Aiden I knew, the one before he went to Atlanta to find you, had always respected and viewed halfs equally, but he never would've taken time away from his Sentinel duties to help any half. And then I saw the way he was around you in New York. It's all in the way he looked at you - the way he constantly looked at you. You were his world, probably before either of you realized that."

Alex: "You could tell all that by the way he looked at me?"

Laadan laughed hen, the sound like wind chimes

Laadan: "He watched you like a man starved for the only think that could fulfill his hunger."

Alex: "I don't think this is the kind of training Apollo had in mind."

Solos: "When's the last time you trained?"

Alex: "I was fighting, like, two days ago."

Solos: "One day in the span of many means nothing. Our muscles need to be used daily."

Alex: "I think they could use your help more. I could be working on using akasha right now. Seth has years of practical experience on me."

Solos: "And you will work with that, but not right now."

Eyes narrowing, I raised my hand.

Alex: "I could just use the air element and knock -"

Aiden: "Alex. I also doubt Apollo meant for your mouth to be the only thing getting a workout."

He released the blades and I caught them.

Waving them in his face, I grinned.

Alex: "I kind of rock at this."

He turned, brows furrowed.

Solos: "I don't even know what that move was."

I flipped the dagger in my right hand

Alex: "It's called being awesome and it worked."

Marcus: "You are my niece. You are my sister's daughter. And you are so much like her ... You were so much like her that when you came back to the Covenant ... and even now, I have a hard time looking at you without seeing my sister."

Alex: "Wait. Is this book about aliens?"

She snatched it back from me.

Lea: "Yes."

Alex: "Really?"

Lea: "But they're hot aliens."

She tapped on the guy's face with one thin finger.

Lea: "And he can be my ET any day."

Alex: "You're in my personal space. Let go."

Seth: "No. You might hit me again."

Alex: "You can count on it!"

Oh, I was two seconds from jumping on his back and strangling him from behind ... with love, of course.

Aiden: "At night, when I'm sleeping, is t he only time I don't think about it - what I did. You ... don't understand. What I did to you - putting you on the Elixir? I don't deserve anything else."

Alex: "You -"

Aiden: "I didn't have to, Alex. It was weak of me. I didn't trust that eventually you'd break the bond. And seeing what it did to you? I can't forgive myself for that."

Alex: "You can't blame yourself for that! You did what was right."

Anger flashed in his eyes

Aiden: "It wasn't right."

Alex: "Aiden -"

Aiden: "The Elixir was one of your greatest fears, Alex! And I did that to you! How ... How is what I did any different than what Seth did to you - is still doing to you?"

Alex: "Putting my on the Elixir isn't the same thing as Seth twisting me into a psychotic Apollyon!"

Aiden: "But I stripped you of who you are, Alex. It's the same. I held you down and forced your mouth open as Marcus gave you the Elixir. You begged for me to stop and I didn't. I watched the Elixir take hold, and it was me who became your Master. I can't ..."

He cut off and turned away.

Alex: "Look, I hate to cut through your self-pity with a big dose of grow-up."

Turning around, Aiden's brows shot up and he opened his mouth

Aiden: "No. You had to make a tough decision. All of you did. I was Evil Alex. And I remember threatening to pull out Deacon's ribcage. I can understand why you did it."

Aiden: "Alex, this isn't about you forgiving me."

Alex: "Then what's it about? I forgive you. Hell, there's nothing to forgive. And if anything, I should be thanking you."

Aiden: "Don't ever thank me for putting you on the Elixir."

Alex: "Ugh! I wasn't thanking you for that. I was thanking you for not giving up on me. For still being there for me when I was acting like a psycho."

He stared up at me, stony as ever.

Alex: "I want to strangle you."

Aiden arched a brow

Alex: "We've all done things that we regret. I'm living with the fact that I threatened everyone that I care about. You have no idea the things I though - the things I believed in - when I was connected with Seth. Or maybe you do, but it's not the same. And if I can get over it, then by gods, you need to get over it. I need you right now, more than ever. And I don't need you to just hold me at night. Even though that's really nice and all,I need you to really be here."

Hurt flashed in his silvery eyes

Aiden: "I am here for you."

Alex: "You're not. You can't be when you're sulking around here, blaming yourself for something you had to do. I need you to man up, Aiden."

Aiden: "Man up? It's a good thing I love you or I'd find that particularly insulting."

Alex: "If you love me, you'd get over this. You'd deal with it, accept that you had to do it, and get past it. Because I'm scared out of my mind, Aiden, and I don't know how any of us are going to survive what's happening. Right now, I need you - all of you. We - we - are more important than your guilt, or at least I thought so, but apparently I'm wasting my breath."

I was really close to to tipping the couch back and dumping him off of it, but he shot up and was in front of me before I could blink an eye. He wrapped an arm around my waist and our eyes locked. Everywhere our bodies touched, heat rushed to the surface. It wasn't like i had forgotten hat it was like to be in his arms, I just wasn't prepared for it.

I could never be prepared for it.

Neither was Aiden. His eyes were burning a liquid silver and his arm tightened around me.

Aiden: "I would never give up on you, Alex. Never."

Alex: "Then why are you being such a -"

Aiden: "What? I'm being what?"

Infuriating. Stubborn. Thick-skulled. Freaking sexy.

Alex: "Good gods, can we stop arguing and just, I don't know, make out?"

A deep, husky laughed rumbled through his body and teased mine.

Aiden: "Is that what you want?"

More than the air I breathed.

Alex: "What do you think?"

He moved forward, backing me up until I was pressed against the closed door.

Aiden: "That I'm seriously in love with your one-track mind."

Aiden: "It's hard, Alex, remembering how you were. I hated it. Hated every moment of it."

I placed my hand on his cheek.

Alex: "I know."

Aiden: "And all I could think about was getting you back."

He pressed his lips to my temple and then the hollow of my cheek.

Aiden: "But you're right. I haven't been here completely."

Alex: "You're not going to feel guilty over that, too?"

He grinned against the side of my neck, his lips moving against my wildly pounding pulse.

Aiden: "You always have to be such a smartass."

Alex: "Are you following me?"

Aiden: "I'm just being here for you, and I think you really need me right now."

Alex: "Ha. Ha."

Aiden's grin spread and a dimple in his left cheek appeared. He tucked a strand of my hair back, then his hands dropped and he tugged the shirt out of my cargos.

Aiden: "I think you called it 'manning up'."
