Margaret Mizushima balances writing with assisting her husband with their veterinary clinic and Angus cattle herd. Her short story "Hayhook" was published in the Rocky Mountain Fiction Writers 2014 anthology, Crossing Colfax. She lives with her husband on a small ranch in Colorado, where they raised two daughters and a multitude of animals.

When a young girl is found dead in the mountains outside Timber Creek, lifelong resident Officer Mattie Cobb and her partner, K-9 police dog Robo, are assigned to the case that has rocked the small Colorado town.

With the help of Cole Walker, a local veterinarian and single father, Mattie and Robo must track down the truth before it claims another victim. But the more Mattie investigates, the more she realizes how many secrets her town 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 debut that will have listeners clamoring for more Mattie and Robo for years to come.
