This story takes place in Melanie Brown's Switcher Universe

The Switcher strikes a group of four friends, scrambling their relationships,
leaving none of them in their own body.

One of the four is Leo, a 42-year-old con man and swindler,
who now finds himself in the body of a thirteen-year-old girl --
a girl with a troubled history of her own.

In spite of his life experience, Leo finds himself dreading the start of high school,
awkwardly entering his first friendship with a thirteen-year-old boy,
enduring the ups and downs of life with the mother of the girl whose life he's living,
and adapting to a drastically different rapport with the friends he had as an adult.

As if that weren't enough, the question remains: What did the Switcher want with him?
