Demon Hunter by Louisa Masters

What happens when the hunter becomes the hunted?

Before that night, there wasn’t much in my life I could complain about. I hunt rogue demons for a living, which is the coolest thing ever, and my brothers are the best. Sure, there was that thing with our parents betraying humanity, and okay, I wasn’t thrilled when my brother-bestie hooked up with a demon, but everything else was amazing.
Except that Dylan, the person I love more than anything, wanted to keep our relationship secret.
I got it; I really did. He’s lost all his family, and he was afraid if my family adopted him, he might lose them too. It’s not like we’ve got the world’s safest jobs. I was sure he’d change his mind eventually.
That decision was taken from him one awful night. Now, everyone knows, but Dylan’s more worried about the people trying to kill me. Unidentified and vicious; that’s all we know. Oh, and they hacked The Collective’s server.
How does a demon hunter fight a virtual threat? He doesn’t… that’s his kickass techie boyfriend’s job. Dylan will find these people, and then we’ll deal with them.

Even if there is more going on than we know about.
