Then, when he least expects it, he encounters Delphy, an older girl who is also lost. Their unlikely friendship grows as they join forces to find civilization. The pace never slows, and eventually flames surround Sam and Delphy on all sides. A powerful bond is forged that can only grow out of true hardship-as two true friends beat all odds and outwit one of the deadliest fires ever. At the end of the novel, information about wildfires and useful safety tips add to the reader's understanding of one of the US's most dangerous natural disasters.
