Pinning a purple flower into her bleach blonde hair, pretty Ava admired herself in the mirror. She had every reason to be proud. In the space of a year, she had lost an incredible 17 stone. Her weight dropped from 37st 1lbs to 19st 7lbs, and she slipped into a dress before gazing at her newly svelte figure. With her smokey eye makeup and black skater dress, she could have been glamming up for a night on the tiles with her girlfriends. Instead, it was Halloween, 2013, and Ava was hiding a huge secret. Born a boy named William, it was the first time she had ever dressed as a girl – and everything fell into place.
