Double-Cross My Heart - Brandon Hill

Turned at a tender age, and left with no memory of her human life, Elisa, the beloved adopted daughter of Talante, has had many obvious difficulties in her near two centuries of life, but none so frustrating as her inability to find love - that is until a dire mission leads her to Derek, another vampire turned in his formative years, and the de facto leader of a clan of vagabonds: vampires who choose to take no sides in the ten millennia long war between her symbiotic clan and the dominating breed of her father's hated enemy. But her happiness is only a prelude to heartbreak as she learns secrets of a past she thought erased, which may cost her the trust and love of the one who holds the greatest portion of her heart.
