The Exterminators (The Exterminators #28)

Part 1 of "Bug Brothers Forever." The bug-god Atan (returned to Earth in the form of Henry's depraved ex-partner AJ) and his army of Mayan Hissers begin a massive attack. They need one last key to open the mysterious box - and the Bug Bee Gone boys have got it. As the Hissers lay waste to Los Angeles, Henry, Stretch and the crew steel themselves for what could be their final, heroic stand.
