When Jake Taylor's mother is left beaten and unconscious by boyfriend Bull, Jake and his younger brother, Taylor, decide it's likely no longer safe to continue living with her. As they learn a little more about Bull, they discover he's a dangerous man tied up in illegal dealings, possibly even murder. Learning this, the Wilder boys take it upon themselves to try to track down their biological father, who abandoned the family years earlier.
As far as figuring out their father's whereabouts, all the boys have to go on is a journal he wrote full of wilderness facts and survival tips, information that will prove quite handy as they make their way across the country looking for him. Jake is also aided by information he retained from attending an outdoor school the previous summer. This trip will take them from Pennsylvania all the way through to the wilds of Wyoming. There's quite the adventure in store for these lads, as they find themselves thrown into a crash course on surviving the elements, scaring off bears, fighting off angry Dobermans, train jumping, and fighting / escaping some violent hobos. At one point there's even a close call with some poisonous berries! But they survive, eventually finding assistance from an unlikely source --- a female trucker / former addict with a criminal record.
As the older brother, Jake naturally falls into the protector role, but secretly is often unsure of himself and his choices. Meanwhile, younger brother Taylor displays an impressive blend of unshakeable optimism and steely determination.
There's a fair amount of violence... and perhaps some questionable characters / material (depending on how strict you are with your child's reading material)... for a Middle Grade audience, but there's plenty of benefit to this series as well. Not only is the adventure itself a well-paced, entertaining read, but this book, as well as its sequel, offers supplemental materials at the end. In the case of Book 1, there's a mini plant identification guide, instructions on how to use glass to start a fire, and how to create and set fish traps.
