Dark prince - Christine Feehan

Carpathians are an immortal race of beings with animal instincts. Every Carpathian male is drawn to his life mate: a Carpathian or human female able to provide the light to his darkness. Without her, the beast within slowly consumes the man until turning vampire is the only option.'

Raven Whitney is a psychic who has used her gift to help the police track down a serial killer. Now she is determined to escape the glare of recent publicity for the peace and quiet of the Carpathian Mountains. Prince Mikhail Dubrinsky is the leader of his people but, as his ancient Carpathian race grows ever closer to extinction, he is close to giving in to the heavy weight of loneliness and despair. From the moment their minds touch, Raven and Mikhail form a connection. But there are those who incorrectly view all Carpathians as vampires, and are determined to give their extinction a helping hand.
