From the #1 New York Times bestselling author of the Percy Jackson and the Olympians series  Rick Riordan, triple-crown winner of the Edgar, Anthony, and Shamus Awards, brings his fast-talking, hard-living, Texas-hip P.I. Tres Navarre to the heart of the Lone Star State—Austin—to unravel a case so dark, twisted, and deadly, it can only involve family.... Tres Navarre, the P.I. with a Ph.D. in literature, heads to Austin for a laid-back summer teaching gig. But he’s in store for a whole lot more. His big brother Garrett--computer whiz, Jimmy Buffett fanatic, and all-around eccentric—is hoping to retire a multimillionaire by the fall. He’s bet his career and the Navarre family ranch to do it. Then Garrett’s oldest friend and business partner is murdered—and Garrett is the only suspect.
