Seton Academic High is a prep school obsessed with its football team and their thirteen-year conference win streak, a record that players always say they’d never have without Seton’s girls. What exactly Seton girls do to make them so valuable, though, no one ever really says. They're just "the best." But the team’s quarterback, the younger brother of the Seton star who started the streak, wants more than regular season glory. He wants a state championship before his successor, Seton’s first Black QB, has a chance to overshadow him. Bigger rewards require bigger risks, and soon the actual secrets to the team's enduring success leak to a small group of girls who suddenly have the power to change their world forever.
Harper Proulx has lived her whole life with unanswered questions about her anonymous sperm donor father. She's convinced that without knowing him, she can't know herself. When a chance Instagram post connects Harper to a half sibling, that connection yields many more and ultimately leads Harper to uncover her father's identity.
So, fresh from a painful breakup and still reeling with anxiety that reached a lifetime high during the pandemic, Harper joins her newfound half siblings on a voyage to Hawaii to face their father. The events of that summer, and the man they discover—a charismatic deep-sea diver obsessed with solving the mystery of a fragile sunken shipwreck—will force Harper to face some even bigger questions: Who is she? Is she her DNA, her experiences, her successes, her failures? Is she the things she loves—or the things she hates? Who she is in dark times? Who she might become after them?
