Hunted: A House of Night Novel by P.C. & Kristin Cast

What's on the back of the book:
The door closed with a sickening thud of finality. Shutting my friends out and leaving me alone with my enemy, a fallen angel, and the monstrous bird creature his ancient lust had created. Then I did something I'd only done twice before in my entire life. I fainted.

It's all happening, though Zoey Redbird wishes it wasn't. She has her friends back, which is great. But a dark angel has taken over the House of Night, supported by High Priestess Neferet. Not so great. This leaves Zoey hiding out with the (supposedly friendly) red fledglings in Tulsa's prohibition-era tunnels. The not greatness continues.

Naturally, Zoey also has boy issues to stress her out, with a chance to make up with super-hot-ex Erik. But thoughts of the archer that died, semi-permanently, in her arms keep distracting her. Then he shows up as Neferet's newest minion. Well, hell. Zoey and friends will need a plan to put things right, and soon, if she can just keep her head and her heart intact.

A piece from the book:
I held my breath and heard his footsteps stop. I still didn't look at him. I was afraid if I did that, I would turn around, run back to him, and hurl myself into his arms.
I was almost to the old metal grate when I heard the first croaking caw. The sound stopped me like I'd run into a brick wall. I whirled around. Heath was standing in the freezing rain under the tree just a few feet from his truck. I spared hardly a glance for him. My eyes darted up into the dark branches of the ice-bowed tree.
Within the shadows of the naked boughs a darkness stirred. It reminded me of something, and I blinked, staring at it and trying to remember where I'd seen something like it before. Then the image shifted . . . changed . . . I gasped as it became more visible. Neferet! She was clinging to a thick, ice-slick branch that leaned against the roof of the depot. Her eyes blazed crimson and her hair whipped around her crazily, like she had been caught in a sudden wind.
Neferet smiled at me. Her expression was so purely evil that I felt frozen in place.
Then, as I stared up in horror, her image shifted again, wavered, and where the image of the tainted High Priestess had been, there was now a huge Raven Mocker. The thing perched on the side of the depot roof wasn't human and it wasn't animal. It was a terrible mutated mixture of both.
