THE FIRST ANNA PIGEON NOVEL

The fascinating hero of Nevada Barr’s award-winning series—park ranger Anna Pigeon—has brought an unyielding love of nature and sense of fair play to the mystery genre. Track of the Cat is the acclaimed novel that first introduced readers to Anna, as a woman looking for peace in the wilderness—and finding murder instead…

Patrolling the remote West Texas backcountry, Anna’s first job as a national park ranger is marred by violence she thought she had left behind: the brutal death of a fellow ranger. When the cause of death is chalked up to a mountain lion attack, Anna’s rage knows no bounds. It’s up to her to save the protected cats from the politics and prejudices of the locals—and prove the kill was the work of a species far less rare…

Anna Pigeon fled the turmoil of New York to become a national park ranger, only to discover she hasn't escaped murder and violence. When a colleague is killed, claw marks on the victim's throat and paw prints around the body are too perfect to be those of an alleged killer mountain lion.
