16-year-old Perry Firekeeper-Birch has every intention of quitting her internship. Being stuck in a museum was never part of her lazy summer plans, but her no-nonsense Aunt Daunis had other ideas. Everything changes when Perry meets 'Warrior Girl', a Native American ancestor whose bones are locked away in the local university's archives. Perry's rebellious spark becomes a righteous blaze, and she will do whatever it takes to bring 'Warrior Girl' home - where she belongs. Taking matters into her own hands, she plots a daring heist with a bunch of misfits. But this uncovers much bigger secrets that Perry and her friends must set right - before their ancestors are lost forever.
