First Drop of Crimson

From the New York Times bestselling author of the Night Huntress series comes a breathtaking new journey to the dark side of desire.
The night is not safe for mortals. Denise MacGregor knows all too well what lurks in the shadows — her best friend is half-vampire Cat Crawfield — and she has already lost more than the average human could bear. But her family's past is wrapped in secrets and shrouded in darkness — and a demon shapeshifter has marked Denise as prey. Now her survival depends on an immortal who lusts for a taste of her.
He is Spade, a powerful, mysterious vampire who has walked the earth for centuries and is now duty-bound to protect this endangered, alluring human — even if it means destroying his own kind. Denise may arouse his deepest hungers, but Spade knows he must fight his urge to have her as they face the nightmare together...
Because once the first crimson drop falls, they will both be lost.
Jeaniene Frost
Jeaniene has always been drawn to the strange. As a child, she and her sisters would watch horror movies at every opportunity. At twelve, she began writing poetry. Shortly after that, she read her first romance novel, and it was love at first read! She knew she wanted to write her own novel someday, but figured she had plenty of time. That same "plenty of time" mentality also lingered past her teens and through her twenties, however. It wasn't until Jeaniene was almost thirty that she realized she'd either have to start now – or resign herself to never doing it.
