Dark Legend - Christine Feehan

For two thousand years Carpathian twins Gabriel and Lucian were vampire hunters. But then, Lucian turned vampire, forcing Gabriel to hunt him. Lucian and Gabriel battled each other for centuries until two hundred years ago, when Gabriel sacrificed his freedom, trapping Lucian and himself in the earth of a Parisian cemetery. Now, modern construction work within the cemetery has disturbed their resting place and Gabriel and his dark brother Lucian are raised from the rubble. Weakened and in desperate need of blood, Gabriel fears he will lose his own soul before he can restore his strength. Fate is on his side when Francesca, a uniquely gifted healer, comes to his aid. Gabriel instantly recognises that she is his lifemate, and must convince Francesca before it is too late: Lucian is on their trail, and will let nothing stand in the way of his eternal conflict with his brother.
