Perry Firekeeper-Birch has always known who she is — the laid-back twin, the troublemaker, the best fisher on Sugar Island. Whilst her overachieving sister works away at an internship, Perry's holiday plans mostly involve doing absolutely nothing. But her carefree summer is brought to an abrupt end when she meets 'Warrior Girl', a Native American ancestor whose stolen remains are being kept in the archives of a local university. Perry is determined to bring her home, with the help of a small group of friends and allies, including her twin sister and a charming new boy in town with unwavering morals. Old rivalries, sister secrets, and botched heists cannot—will not—stop her from uncovering the mystery before the ancestors and missing women are lost forever.
