Track of the Cat (An Anna Pigeon Novel)

The Anna Pigeon series is built on a fascinating concept: each mystery is set in a different national park. In book one, Anna runs from her past and moves from New York to the Guadalupe Mountains of West Texas to be a park ranger. When her fellow ranger and friend Sheila is killed by a mountain lion, Anna notices some discrepancies. The claw marks and paw prints are too perfect, and Anna suspects foul play. Anna treks the land to find the real killer. The author was a park ranger herself, and her experience is evident on the page.
