Stinger

McCammon's novel "takes place during a single twenty-four hour period in Inferno, Texas. Inferno is a town in trouble, driven to the brink by racial tension, gang violence, and a collapsing economy. But things can always get worse, and they do so with astonishing speed when an unidentified spacecraft crash lands in the desert outside of town, followed by a second craft bearing the alien being who will soon be known as Stinger. Stinger is a kind of interstellar hunter on a mission he intends to complete, whatever the cost. He brings with him an endless array of technological marvels and an infinite capacity for destruction that threaten the existence of Inferno, its inhabitants, and the larger world beyond"--Dust jacket flap.
