Showing Dark Melody by Christine Feehan

Dayan has been searching for centuries to find the one woman who can complete him, a true lifemate, who can save him from the darkness in his soul. Despairing of ever finding her, and on the run from his enemies, something drives Dayan to stop at a bar and perform some of his music. Then Corrine Wentworth walks in, and Dayan knows instantly that she is the one. Corrine wants nothing more than to surrender her life and soul to Dayan, but she is suffering from a degenerative heart disease, and pregnant with her late husband's child. She is also running from the men who killed her husband, the same group of fanatics who are hunting Dayan and his kind. Dayan must call on his family, and the greatest healers of the Carpathians to aid him in a race against time to save Corrine, whose fate is now inextricably linked to his own.
