Hailey balances on the lip of a brick wall between yards, miles from the Dursley home.
No one knows that name. If she doesn't escape some day, no one's going to. She's had ideas about stealing hormones, or stealing money and buying hormones, or some other way, but it all comes down to hiding everything about this from her aunt and uncle.
She's six and nobody explained the difference between boys and girls but what few friends she has are girls and she wants to be a girl. She tells her aunt this, and gets a horrified gasp in reply.
When her uncle gets home, he takes off his belt. Grabs her and drags her to the couch.
Sharp, burning lines of pain across her back, across her butt.
It's far from the first or last time.
She stumbles a moment as she hops from one wall to the next, gasping at the sharpness of the memory.
