Dark Peril (Dark, book 21) by Christine Feehan
'Carpathians are an immortal race of beings with animal instincts and the ability to shape shift. Every Carpathian male is drawn to a life mate: a woman - Carpathian or human - able to provide the light to his darkness. Without her, the beast within slowly consumes the man until turning into a vampire is the only option.' In Feehan's latest, lose yourself in one man's gripping battle to save himself and his search for the one woman who will answer all his prayers...as well as satisfy his desire.
