First Responders

From the back of the book: A fire roars through an apartment building. Rescuers struggle through surging flames to reach stranded families—but meanwhile, sparks drift over the nearby gas station. A train derailment has toppled a truckload of nuclear waste, exposing trapped passengers to the dangerous radiation. But reaching them risks shifting the wreckage—and spilling even more. A grumbling volcano threatens efforts to rescue lost hikers. When the lava begins to flow, whole towns are suddenly at risk!
