Darkness Calls (Mills & Boon Intrigue) (The Calling, Book 1)

Falling Prey to Passion FBI agent Diana Reyes knew too much about the darkness of the human soul. She had spiraled into that underworld once before–and vowed never to fall again. Until she met him. Powerful, dangerous and the key to catching a psychotic killer, Ryder Latimer was everything she couldn't have–and everything she wanted. He haunted her nights, shattered her reserve and made her feel…more than she ever had before. But once she learned his secret, would his sensual promises of eternal love be enough to garner her forgiveness? For Ryder was more than a lover of the night…he was a vampire.
