'Winning heroine . . . strong debut . . . a realistic view of how a K-9 team works, treating Robo as an important character, but never stooping to anthropomorphism. And it's impossible not to fall in love with Robo.' Publishers Weekly

A young girl is found dead in the mountains near Timber Creek, Colorado. Officer Mattie Cobb and her partner, K-9 police dog Robo, are assigned to the case that has rocked the small town in Margarat Mizushima's first K-9 mystery, Killing Trail.

With the help of Cole Walker, local veterinarian and a single father, Mattie and Robo must track down the truth before the murderer claims another victim. But the more Mattie investigates, the more she realizes how many secrets her hometown holds. And the key may be Cole's daughter, who knows more than she's saying.

The murder was just the beginning, and if Mattie isn’t careful, she and Robo could be next. Suspenseful and smart, Killing Trail is an explosive crime thriller from debut author Margaret Mizushima.
