It's a beautiful day for a war.

As the mortal world slowly slips into chaos of the godly kind, Alexandria Andros must overcome a stunning defeat that has left her shaken and in doubt of their ability to end this war once and for all.

And with all the obstacles between Alex and her happily-ever-after with the swoonworthy Aiden St. Delphi, they must now trust a deadly foe as they travel deep into the Underworld to release one of the most dangerous gods of all time.

In the stunning, action-packed climax to the bestselling Covenant series, Alex must face a terrible choice: the destruction of everything and everyone she holds dear… or the end of herself.

Oh. My. Gods.

Sentinel by Jennifer L Armentrout is the fifth, and final *sob* book in the Covenant series. Sentinel starts up immediately after the end of Apollyon, with Alex waking up after her stunning defeat left both her body and spirit broken. While Alex tries to deal with the physical and mental scars of her trauma, she is also forced to continue to fight in the war against Ares. In order to weaken their enemy, they are forced to enter the Underworld once again, and release one of the most dangerous gods of all time to help.

Wow. I'm left stunned. This was an insane, epic, conclusion to Alex's story. Sentinel blew all of my predictions away. The book itself, the whole series, is so wonderfully original, and fresh in a genre what tends to be copy, paste, repeat. Sentinel didn't skimp on the action, but it also didn't pass over on the emotional content. Love and heartbreak. Happiness and sorrow. Sacrifice. Sacrifice is the big one here, because everyone, especially Alex, is forced to give up something in order to get ahead in the war. By the end of the book, and sadly, the series, I'm left with an emotional hangover.

Alex has grown up. Despite her brutal defeat in Apollyon, she continues on. Knowing in the end, if she does what the gods want, and becomes the God Killer and takes down Ares, she will very likely be taken out as well, she still goes on to do whats right, and despite all the bad things that have happened to her and around her, she hopes. Alex may be feisty, temperamental, and sometimes a little selfish, but she is also incredibly loving, and loyal. She will do anything for those she loves. She's not fearless, but does what needs to be done. And Aiden ... oh be still my beating heart. Ever since admitting that he loves Alex, his happiness radiates whenever she is near ... even when he probably wants to strangle her. Their chemistry is beautiful, and admittedly, steamy as hell. Aiden's calm personality is the perfect pairing with Alex's fiery one, but he can come out and become unstoppable when he needs to. We can't forget about Seth. I am so glad I had hope for him, because somehow he wiggled his way back in, made me root for a happy ending for him, while still maintaining his arrogant, douchy personality. Seth has come a long way, and by the end, he has learned a lot from Alex, despite him being the First. He was always brave and strong, but Alex taught him a whole new meaning to those words.

My face is still puffy from that ending. It's bittersweet for sure. With war comes death, and we lose some. Some get a happy ending, and some don't. And while Alex's story is done, Seth's isn't. There is a spin-off series starring how favorite bad boy Apollyon, and I'm crossing fingers good things come to him, and we get to see some of our favorite characters again. Jennifer L Armentrout is a phenominal writer, and I promise you, you will not regret picking up the Covenant series.

Favorite Quotes

Aiden: "Alex."

My heart skipped a whole beat, and then sped up in recognition. Ah, I knew that voice. My heart and my soul knew that voice.

Aiden: "Alex, open your eyes. Come on, baby, open those eyes."

A warm, strong hand curved along my cheek; the touch was so different than my mother's, but equally powerful and heartbreakingly tender. My breath caught in my throat. His thumb traced the curve of my jaw in such a lovingly familiar way that I wanted to weep.

Aiden: "It's okay. Apollo said it could take some time. I'll wait for however long it takes. I'll wait forever, if I have to."

He was my strength when I needed him to be, my friend when I needed someone to talk me down, my equal in a world where by law I would always be less than him, and honest to gods, he was the love of my life.

And he would wait forever for me, just as I would wait forever and a day for him.

Aiden: "I know why you made sure Marcus and I were out of that room when Ares attacked. It was incredibly brave, and so like you. But if you ever do anything like that again, I will strangle you. Lovingly, of course. We promised each other we'd face this stuff together."

Alex: "Ares would've killed you."

Aiden: "But I would've protected you. I would've done every godsdamn thing there was to save you from having to go through what you went through in there. When I came into the room and saw you ..."

He broke off, cursing under his breath.

Alex: "You would've died trying to protect me. Don't you get that? I had to do it. I couldn't live with myself if you or Marcus died -"

Aiden: "And do you think either of us can live with ourselves knowing what that bastard did to you? Look at me."

I shook my head

Aiden: "Godsdammit, Alex, look at me!"

Startled, my head jerked up and my eyes met his. They were a furious shade of gunmetal gray, and they were so open. Raw pain flowed from them, and I wanted to look away from that, to take the coward's way out.

Aiden: "My heart stopped when that damn door closed on me. I could hear you two fighting. I could hear him taunting you, and I could hear him breaking your bones. And there wasn't a damn thing I could do about it."

He placed his hands on the sides of my legs. Tension rippled through the muscles in his arms.

Aiden: "You never should've face something like that alone."

Alex: "But you would've died."

Aiden: "And because I love you, I am willing to die to save you from that. Don't you dare take that decision away from me again."

Aiden: "Stop being so stubborn, Alex."

Alex: "You're the one who's being pigheaded."

I tried to pull free, but Aiden held on, a warning flaring in his eyes.

Alex: "I'm trying to protect them."

Aiden: "I know. And that's the only reason I'm not throwing you over my shoulder and locking you in a room somewhere."

My eyes narrowed

Alex: "I'd like to see you try."

Aiden: "Is that a challenge?"

Someone in the back of the common area cleared his throat.

Person: "So I'm assuming these two have some sort of past?"

Deacon choked on his laugh as he plopped down on the sofa

Deacon: "That would be an affirmative."

Aiden's gaze slid to his brother, and he took a long, nice, deep breath.

Deacon: "Wow."

Deacon elbowed Luke.

Deacon: "This would be awkward if it weren't so entertaining. It's like watching our parents -"

Aiden and Alex: "Shut up, Deacon."

Deacon: "See! They're like peas and carrots."

Alex: "I look like Frankenstein."

Aiden: "You're beautiful."

Alex: "I look like Frankenstein with a beauty-school-dropout haircut."

Our eyes locked again

Aiden: "You've never been more beautiful to me than you are right now."

Aiden: "Did you feel that?"

Alex: "Yes."

His lips curved into a one-sided smile.

Aiden: "I was kind of hoping you'd say you didn't so I'd have a really good excuse to kiss you again."

My fingers dug into his arms

Alex: "You don't need an excuse."

Aiden: "Alex."

There was a soft warning in his voice.

Alex: "What?"

His head tilted to the side, causing his nose to brush mine.

Aiden: "You don't know what you're doing?"

I almost laughed

Alex: "I know exactly what I'm doing."

Aiden: "Gods ..."

Aiden cradled my cheek as he shifted my hips closer to his. My stomach dipped in such a pleasant way.

Aiden: "You've been through a lot. You're still healing and -"

Alex: "And what?"

Aiden: "I'm not perfect. I only have so much control. And if you keep kissing me like that, we won't even make it somewhere private."

Alex: "And there's something wrong with that?"

Aiden: "No. Yes."

He pressed his forehead to mine, and the once-wonderful dipping motion suddenly twisted.

Aiden: "You've been -"

Alex: "I'm okay. I'm better than okay when I'm like this with you. I need this. I need you, Aiden. Please don't - "

Aiden's mouth crashed into mine. Whatever I had said was like finding the map to a treasure. Bam. Right there. Hiss kiss swept me up into a place where I wasn't thinking. There was no Ares. No looming battle to plan for. No Seth. No pain or fear. All I felt was warmth and love and Aiden.

All I felt was him.

Aiden: "You are a lot of things, Alex. Strong. Brave. Beautiful. Incredibly sexy. But you are not fine. You and I both know that."

My jaw dropped open

Alex: "Holy crows ..."

Luke: "There's a couple of eagles mixed in there."

Aiden: "And a few hawks."

I rolled my eyes.

Alex: "Okay. Holy birds of prey! Is that better?"

Aiden; "Much."

Luke: "That was so Resident Evil. Awesome."

I cracked a grin, a little breathless.

Alex: "It was kind of Alice awesome, wasn't it?"

Aiden: "They won't get past us. Have half of us form a line several yards back. The rest of us will stay here."

Luke: "That would be the oh-shit line."

Alex: "Um ... I really hope this has a point, because half the guys are staring at us like they're hoping we're going to make out."

Aiden coughed.

Alex: "I think you spend your spare time studying a book full of the right things to say."

Aiden: "Nah. I just love you, Alex."

Aiden: "We need to press pause for a second."

I knew I couldn't have heard him correctly, because he moved his leg in a way that had me trembling, then kissed me again, nipping at my lower lip.

Aiden: "Seriously, we need to talk for a second."

A small grin pulled at my lips

Alex: "Then stop kissing me."

Aiden: "That's an excellent idea."

He pressed his lips to the sensitive spot under my ear.

Aiden: "Yet so incredibly hard. I want to talk to you about something."

Alex: "Okay. About what?"

Aiden: "About what Artemis said to you out there today."

Alex: "About my hair?"

He shot me a bland look

Aiden: "No. When she said there was something inside you."

Alex: "Oh. That? Weird, right? Apollo's son - Hippo-whatever - said the same thing when I was in Olympus. I have no idea what they're talking about."

Aiden: "You don't?"

Alex: "No. Do you?"

Aiden opened his mouth and closed it. Several seconds passed, and then he thrust his hand through his hair, scratching his head.

Aiden: "Think about it, Alex."

Alex: "Enlighten me, wise one."

Aiden: "You're really going to make me say it?"

He swore under his breath as his hand fell to his lap

Aiden: "Of course you are. Don't you think there could be a possibility that whatever Artemis felt, or saw or whatever, means you're ... pregnant?"

I stared at him

Alex: "What?"

Aiden: "Pregnant."

Alex: "No."

I coughed out a laugh and rolled my eyes

Alex: "No way."

Aiden looked at me like I was half-stupid.

Alex: "What? There's no way it could be that, because that just isn't possible. I would, like, know if that was it, and I would totally be ..."

Oh my gods in Olympus ...

I sat up, nearly knocking Aiden off the bed. My eyes were wide.

Alex: "Pregnant? Bun in the oven? A little Alex or Aiden running amuck? Okay. A little you would be so adorable, but preggers? Oh gods, have I told you how much I hate the word 'preggers?' Like, is 'pregnant' such a long word that you have to shorten it? I feel the same way about 'hubby.' Seriously? Hubby and preggers are the stupidest -"

Aiden: "Alex, whoa. Slow down. Take a breath."

Alex: "It can't be that, can it?"

Aiden: "It could be, Alex."

Aiden: "I know this isn't happening at a good time."

I did laugh at that.

Alex: "Yeah, that would be horrifically bad timing."

Aiden: "But would it be so bad?"

Alex: "You would be okay with this?"

Aiden lowered his gaze for a moment and then shifted so he was sitting in front of me. He took my hands in his, and I suddenly realized how serious this was.

Aiden: "This isn't the right time for us. Not with everything going on, but ... but how could I not be okay?"

I was actually speechless. Someone needed to record this moment

Aiden: "I love you, Alex. That's never going to change, and although neither of us is ready for this, I can get ready for this. Both of us can, and we will face this together. I can't be that bad at being a father. I mean, I basically had to raise Deacon, and he's still alive."

Alex: "You're perfect."

Aiden: "I'm not perfect. I just can't be that upset over the fact that we might be having a baby."

Aiden: "I really do like the hair. But you could be bald and I'd still think you were hot."

I made a face.

Alex: "My ears are huge. That would not be attractive."
