Saguaro Sanction is the latest book in the acclaimed National Park Mystery Series by National Outdoor Book Award-winning author Scott Graham.

The series is published by Torrey House Press and features the husband-wife amateur sleuth team of archaeologist Chuck Bender and paramedic Janelle Ortega. The eight books in the series have been praised by a host of national publications and award-winning mystery authors as “masterful,” “rewarding,” “intriguing,” and “brimming with heart.”

Saguaro Sanction—“the best book in the series so far” according to one reviewer—introduces readers to the landscapes and cultural history of Saguaro National Park in southern Arizona, providing an inside look at the wonders of the park and its archaeological and sociological complexities.

When Janelle’s cousin from Mexico is found brutally murdered at a remote petroglyph site in the park, she and Chuck are drawn deep into a threatening web of hostility and deceit stretching south across the US-Mexico border and back in time a thousand years, to when the Hohokam people thrived in the Sonoran Desert.
