Jennie's awkward teenage life is upended when she discovers she's not a boy. With her parents divorced, her father missing, and finding herself falling in love with Gabby, she's got enough to deal with already. The only way out of spiraling anxiety is to learn about gender identity and become Jenny Heckenlaible. With help from her girlfriend, school counselor, doctor, and mother, she charts a path to self-discovery and gender euphoria. Jenny secretly blogs about what led to her revelation and everything it took to become a Heckenlaible. When the class bully finds her blog, she calls in favors from Greenfield Central High's queer community to help her make it to graduation. Jenny's transformation spans four years, from her gender awakening to becoming a visible advocate for her trans community.
