Raise your margarita to Rick Riordan for the authentic portrait of his hometown, San Antonio, in The Last King of Texas , his third Tres Navarre mystery. This time out, Navarre finds himself embroiled in an open-and-shut case that won’t stay closed. Engagingly cast with the likes of boss Erainya Manos and detective Ana DeLeon, this tale of revenge and remorse sizzles and skids like drops of water on a hot skillet.  by Mike Shea
