Being connected to Daemon Black sucks…

Thanks to his alien mojo, Daemon’s determined to prove what he feels for me is more than a product of our bizarro connection. So I’ve sworn him off, even though he’s running more hot than cold these days. But we’ve got bigger problems.

Something worse than the Arum has come to town…

The Department of Defense are here. If they ever find out what Daemon can do and that we’re linked, I’m a goner. So is he. And there’s this new boy in school who’s got a secret of his own. He knows what’s happened to me and he can help, but to do so, I have to lie to Daemon and stay away from him. Like that’s possible. Against all common sense, I’m falling for Daemon. Hard.

But then everything changes…

I’ve seen someone who shouldn’t be alive. And I have to tell Daemon, even though I know he’s never going to stop searching until he gets the truth. What happened to his brother? Who betrayed him? And what does the DOD want from them—from me?

No one is who they seem. And not everyone will survive the lies…

HANDS DOWN, feet down, face down, ass down the best book Jennnifer L. Armentrout has ever written (yes, the extra "n" in Jennifer was originally a typo, but I decided to leave it in because that's just how awesome she is).

"People who didn't heart books didn't understand".

I would have to agree with Kat on this one, for anyone who isn't an avid reader will never understand the power of a single book and how it can be treasured among the finest jewels on earth. They are created from the guts, dreams and dri ...more

It might have been because I understood the human better than the bad aliens that they were fighting i ...more
