In the spring of 1885, seventeen-year-old Jessilyn Harney finds herself orphaned and alone on her family's homestead. Desperate to fend off starvation and predatory neighbours, she cuts her hair, binds her chest, saddles her beloved mare, and sets off across the mountains. Her goal? To find her gun-slinging fugitive brother Noah and bring him home. Jess's quest lands her in the employ of the territory's violent, capricious governor, whose militia is also hunting Noah - dead or alive. Wrestling with her brother's outlaw identity, and haunted by questions of her own, Jess must out-manoeuvre whose who underestimate her, ultimately rising to become a hero in her own right.
