All 18-year-old Briar Greyson wanted was to figure out the whole living-away-from-your-parents thing. Apartment, steady job, cool roommate? Check. Noah, her gorgeous (albeit elusive) boyfriend? Check. Everything in her life was pretty good.

Then she and her roommate are attacked on their way home one night, and Briar wasn't supposed to survive. 

Instead, according to the two guys who saved her, she's turning into the things that attacked her: a vampire. Totally crazy and not okay. Now Noah's secrets are coming to light, and he wants Briar dead. Then there are the vampires who attacked Briar to lure out her sister...who died years ago. 

(Didn't she?) 

The city's body count is rising, and Briar wants to help put a stop to it. But first, she has to figure out who the real enemy is: the vampires, the boy she loves, or the sister she thought she'd lost.
