Colt, Blue and Jacob didn't intend to travel to Tydannon this time. Truly, they didn't, but something went wrong when they tried to give their friends Clarence, Butch, Achilles, Cordova, Draven and Cesar a look. The boys are pulled into Tydannon, somewhere in the vast Great Wood with little idea of where they are, no supplies and no idea about how they will get home or even if they can. Their only option is to explore, try to figure out where and when they are, and attempt to discover a way back before their parents discover they're missing and they end up in the biggest trouble they've ever managed to get themselves into.
