An inspiring memoir of defying the odds from Kareem Rosser, captain of the first all-black squad to win the National Interscholastic Polo championship. Born and raised in West Philadelphia, Kareem thought he and his siblings would always be stuck in "The Bottom", a community and neighborhood devastated by poverty and violence. Riding their bicycles through Philly's Fairmount Park, Kareem's brothers discover a barn full of horses. Noticing the brothers' fascination with her misfit animals, Lezlie Hiner, founder of The Work to Ride stables, offers them their escape: an after school job in exchange for riding lessons. What starts as an accidental discovery turns into a love for horseback riding that leads the Rossers to discovering their passion for polo. Pursuing the sport with determination and discipline, Kareem earns his place among the typically exclusive players in college, becoming part of the first all-Black national interscholastic polo championship team-all while struggling to keep his family together. Crossing the Line: A Fearless Team of Brothers and the Sport That Changed Their Lives Forever is the story of bonds of brotherhood, family loyalty, the transformative connection between man and horse, and forging a better future that comes from overcoming impossible odds.
