"In Ray Anderson's Sierra, hard drugs are muled by thugs along the Pacific Crest Trail. No one has a clue until Awol and his mutt, Blazer, step into a hornets nest involving Mexico's biggest drug cartel. Anderson takes you through a scenic nightmare of greed, treachery, and death that isn't resolved until the last page." —Gary Braver author of Tunnel Vision and Gray Matter

"Ray Anderson has done it again. His second book, Sierra, is a fast-paced thriller that will take you hiking across the arid deserts and up the soaring peaks of the Pacific Crest Trail, all while chasing and being chased by a ruthless smuggling ring using the trail to run drugs. Lace up your boots."—Vincent H. O'Neil, author of Glory Main

"“Like Ray Anderson’s first novel The Trail, his new Awol thriller (named for his pseudonymous thru-hiking protagonist) is tense, twisty, and steeped in details that only an experienced long distance hiker could put on the page. Anderson brings the danger and excitement of the remote Pacific Crest Trail fully to life. More than that, he tells one hell of a story. For fans of outdoor mysteries, Sierra is sure to satisfy."—Paul Doiron, author of Widowmaker
