Becca Soloway's perfect summer goes up in smoke when her mom flees a looming divorce by dragging Becca to a Montana resort. To make matters worse, her mom's hasty booking lands them not at a spa, but an aging dude ranch called Far Away.

Becca is miserable until she meets the wrangler's son, Jon, who shows her what might be the first clue to a century-old mystery: the lost treasure of a Robin Hood-like outlaw known as Pearlhandle Pete.

As they slowly uncover the true history of Pete, venture into the mountains, search haunted ghost towns, and are threatened by a treasure-hunter-social-media star, Becca discovers that treasure is in the eye of the beholder and the important things in life are always worth fighting for.
