The world divided by Piper

"Eleven-year-old Piper has big plans. First, she'll win the Academic Decathlon with her best friend, Tallulah. Then, she'll finish her life's work: Metaphorical Math. And in the meantime, she and Tallulah will maintain their secret, El Jard?n Muerto. Nothing can stop Piper. Nothing . . . except for puberty. But Piper doesn't have to worry about that because her body has been on pause ever since she started blockers to delay her early-onset puberty. Based on seeing her older sister struggle with body changes, her mother's attempts to balance too many demands, and the way all the women in her life are too often dismissed, Piper is definitely not excited to grow up. But when Piper's doctor says it's all right to stop treatment, everything is thrown off course. Will a changing body change all of Piper's plans? And why does she have to grow up in the first place? Or does she?"--Provided by publisher.
