Bridgewood is having one of the hottest summers on record. Despite the strict fire ban, fires keep breaking out, and it's starting to look like arson. Dylan O'Connor, as usual, is right in the thick of things, and his friend Eliot is questioned as a suspect. Dylan doesn't think Eliot is the culprit, but he does know Eliot has a secret. He has been providing shelter for a scruffy stranger named Jeb Wilder, aka Wildfire. Is Jeb responsible? Or could it be the guy Dylan caught smoking in the woods, local baseball legend Mason Bates? It's up to Dylan to solve the mystery before the fires get out of control.
