Brothers Jake and Taylor Wilder have been taking care of themselves for a long time. Their father abandoned the family years ago to live off the grid in Wyoming and their mother is too busy working and trying to placate her abusive boyfriend , Bull, to spend a lot of time with them. The boys’ fear of Bull quickly escalates when they witness him shooting another man and beating their mother so badly she’s taken away in an ambulance. The boys grab a bundle of cash that Bull had hidden and set off from their home in Pennsylvania to reconnect with the father they barely remember. With their dog Cody at their side, the boys pore over their father’s journal, full of wilderness tips and survival advice, for guidance. Using old letters they discovered that their mother never gave to them, Jake and Taylor believe they can find their father in the Wyoming wilderness before Bull catches up to them. They hop a freight train, hitch a ride with a sympathetic trucker and stow away in the luggage compartment of a bus, finally arriving in the Grand Tetons. When their path crosses that of a rugged naturalist named Skeet who believes he may have met their dad, the boys learn key skills they’ll need to find their dad before Bull finds them. This first in a fast-paced adventure series will captivate readers with twists and turns on every page.
