Seventeen-year-old Arin Andrews shares all the hilarious, painful, and poignant details of undergoing gender reassignment as a high school student in this winning memoir.

In his captivatingly witty, honest voice, Arin reveals the challenges he faced as a girl, the humiliation and anger he felt after getting kicked out of his private school, and all the changes—both mental and physical—he experienced once his transition began. Arin also writes about the thrill of meeting and dating a young transgender woman named Katie Rain Hill—and the heartache that followed after they broke up.
