Dark Eyes: White Lies (The Dark Eyes) by MR Noble

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.
