Growing up playing on a top national soccer team in the 1980s, Kelcey Ervick and her teammates didn't understand the change they represented. Title IX was enacted in 1972 with little fanfare, but to seismic effect; between then and now, girls' participation in organized sports has exploded more than 1000%. Braiding together personal narrative, pop culture, literature, and history, Ervick tells the story of how her adolescence was shaped by this boom. She also explores her role as a goalkeeper-a position marked by outsider status and observation-and reveals it has drawn some of the most famed writers of our time. With wit and poignant storytelling, The Keeper brings to life forgotten figures who understood the importance of athletics to help women step into their confidence and power-and push for equality. It is is a celebration of how far we have come and a reminder of how far we have to go.
