The 9th Girl
On a frigid New Year’s Eve in Minneapolis, a young woman is found brutally murdered—the ninth so far this year in a string of grisly slayings. Homicide detectives Sam Kovac and Nikki Liska fear that it’s the work of a serial killer they call Doc Holiday, a transient who has brought his gruesome game to a new and more terrifying level. But as Kovac and Liska uncover the truth, they find that the monsters in the ninth girl’s life may live closer to home. And even as another young woman disappears, they have to ask the question: Which is the greater evil—the devil you know or the devil you don’t?

Tami Hoag
Tami Hoag is the #1 international bestselling author of more than thirty books published in more than thirty languages worldwide, including her latest thrillers—THE BITTER SEASON, COLD COLD HEART, and THE 9THGIRL. Hoag first hit the New York Times Bestseller List with NIGHT SINS, and each of her books since has been a bestseller.
When she penned her first work of fiction, a third grade project about two children and a pony, she never imagined she would eventually have more than forty-million books in print all over the globe. “It’s an amazing thing to have people tell me they’ve seen my books in India, in China, on remote Greek islands. Writing is such a solitary, all-consuming pursuit. I sit in my office with my dogs for company, having conversations with imaginary people, and touch the hearts and minds of real people on the other side of the world. That’s incredible to me.”
