She's the only one of her kind. And she doesn’t even know her name. Two investigators—one human, one vampire—find a young woman among a mass of dead bodies. She has no memories, and nothing but her clothes, two receipts, and a mysterious dagger carved with the initials ‘SB’. As she seeks her identity, SB realizes she's unlike any other creature in the world, making her the most valuable person on the planet. And the most wanted. WARNING: Language, violence, and graphic sex.
