“Strong from the Heart,” by Jon Land (Forge) Fans of Jon Land’s thrillers featuring fifth-generation Texas Ranger Caitlin Strong will be pleased to hear that the new book in the series is a lot like the first 10 as the hero, a cross between Wild Bill Hickok and Wonder Woman, dispatches a series of Bond-villain wannabees with extravagant use of gun play and explosives. “Strong of Heart” does differ from its predecessors in one respect, however: It is better written.
