The Fire Keeper's Daughter by Angeline Boulley
"Eighteen-year-old Daunis Fontaine has never quite fit in, both in her hometown and on the nearby Ojibwe reservation. She dreams of a fresh start at college, but when family tragedy strikes, Daunis puts her future on hold to look after her fragile mother. The only bright spot is meeting Jamie, the charming new recruit on her brother Levi’s hockey team. Yet even as Daunis falls for Jamie, she senses the dashing hockey star is hiding something. Everything comes to light when Daunis witnesses a shocking murder, thrusting her into an FBI investigation of a lethal new drug."
