Blindsided by an attack that destroys her home and blamed for murder, Karolina Dalca, a half-vampire, escapes, only to plunge into the magical societies from which she was sheltered. Betrayed by those around her, she abandons her dreams of becoming an investigator and flees, trusting only herself. Her police internship would never prove more useful. Hoofing it through the wilderness, she makes it to her university dorm, disheveled but delightfully deflowered. Enter a full vampire: one wielding dark magic and a ride out of Canada. A fugitive from the law, Karo complies with his demands to escape, unsure whether his requests are bewitched. She vows to clear her name and avenge her mother's death, but Karo's family secrets aren't so easily left behind.

Blackmailed into espionage, Karo must lie to one man while she fights her cravings for another. As spy partners, Karo is forced to work with Andre, the vampire she swore to never trust again. The accidental vampiric bond they have threatens to bend her into submission. But is her will actually weak, or does she want an excuse to give in? Roman’s patience teeters on Karo’s deception. Bitter, desperate, and vengeful, Karo dutifully completes her missions while withholding data from her uncle Loukin’s operation. She swore to get out from under his thumb, even if she has to break a few hands. Each assignment brings her closer to uncovering his goal, and using it against him, but she also draws closer to new foes. And they all want the same thing—Karo’s secrets.
