Onyx by Jennifer L. Armentrout

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…"

Thing are getting hotter in the second book of the Lux Saga! First of all, in the first pages is the famous "Want a cookie? Come and get it!" where Damon holds the cookie in his mouth and he wants Katy to take it and asdf <3 !!! 

  But they are starting to get in a lot of fights because of Blake. Blake? Blake is like Katy, has been alien-marked when he was young, and when he discovers that Katy is one of his kind he proposes to train her. She accepts because she wants to learn how to control and use her powers to help Daemon and Dee in their fight against Arums. But Daemon is jealous (and he is so cute when he is jealous <3 ). Katy strats to control her power and make objects levitate and move around the room. 
   But Arums aren't the biggest problem because DOD is after her and Daemon because of their link. Once they are sure Kat and Daemon are linked there isn't a way out: they are doomed. And most of it is beacuse        Katy saw someone that shouldn't be alive, and I think you've already figured it out who: Beth. But how and why? 
   Also, she is starting to fall really hard for our sexy alien boy! So much that she is confused and she tried to deny the feelings and make them go away. But really, who could say "no" to Daemon Black?
   And if these problems weren't enough for her, her mom made a new boyfriend, a really suspicious one!
   So... Onyx is awesome, Daemon is awesome, but most of all, JLA is awesome!
