Taming Seraphine by Gigi Styx

They captured me, broke me. Molded me into their perfect weapon. I sullied my soul, seducing and murdering strangers. Then a hitman killed my captors and set me free. Leroi: I rescued a girl from a basement thinking she was innocent, but I brought home a serial killer whose darkness borders on insanity. Now, I need to tame her murderous instincts before I become her next victim. Seraphine is reckless, unstable, and likely to get us both destroyed. Every instinct says I should end her, but she’s too captivating to resist. Each day, she draws me deeper into her web, her allure stripping my self-control. But I’m harboring secrets treacherous enough to add me to her list of men to slaughter. Seraphine: Leroi is dark, deadly, and dangerously attractive. I don’t know what he wants, but resisting him is impossible and I'm ready to slay him at the first sign of betrayal. When a dark figure from the past rises from the shadows, wanting to reclaim me, I'm forced to trust a man who might stab me in the back.
