Justice has never known freedom. She woke up ten years ago, naked and alone with no memory of who or what she was. Since then, she's been a prisoner, compelled by powers she doesn't understand. She's roamed the country, doing whatever the fates demanded of her, good or bad. Completely alone.

Until now.

Ronan is starving to death. Like all the Sanguinar, his survival depends on finding the dwindling traces of blood left behind by an ancient, magical race. Weeks ago, Justice saved his life and since then, it's been her blood he craves, her face he dreams about.

As evil closes in on all sides, threatening the only stronghold the Sentinels have to protect them, Ronan must find a way to gain Justice's trust and free her from the dark powers that control her. Because if he can't, the next person she is compelled to kill may be him.
