Harley Locke is no stranger to darkness, but when the irresistibly hot and broody new guy crashes into her world, she isn't sure she'll survive him.

She has one year before she can take her kid-sister and escape their volatile home life, and she'll do anything to protect her-including accepting her supernatural heritage that has every demon in Chicago chomping after her rare blood.

Draven Reid has spent the better part of a century searching for the Key to opening the Gates of Hell so he can rescue his wrongfully imprisoned twin brother, and he's prepared to shed blood to do it. But soon the person he's prepared his whole life to kill turns out to be the one person who makes him feel alive.

Dodging an abusive father, demons prepared to drain her dry, and a newly formed love that may be the death of her, Harley will have to decide on her own what's worth saving: the world that has done nothing but chew her up and spit her out, or the boy whose stolen her heart, but has a blade with her name on it.
