Unchained

Between the pissed-off creatures that want her dead and the fallen angel who just wants her, Nephilim and demon hunter Lily Marks is ready for a quiet 20 minutes with her favorite hamburger. If only her life could actually be that simple.
It's bad enough that she's even civil with a fallen angel like Julian. She's supposed to kill his kind, not flirt with the possibility of daringly-hot sexy times—and he puts her job at the Sanctuary at risk. And now that she's a suspected traitor, it's just a matter of time before "my life is complicated" becomes "here's hoping I survive the night."
Everything is on the line, and Lily's running out of time to uncover the real traitor—and she'll need Julian's help. That is, if he's really there to do good. Because being a Nephilim isn't everything it's cracked up to be...especially when Lily's top priority is staying alive.
