After a family tragedy, young David decides to live by himself in his home where he can be his true self, Katie. It's almost like a dream as Katie explores her new life.

But it's not easy. Where will she get money? How can an eleven-year-old deal with something as mundane as shopping when at any moment some adult may decide she needs help from police, doctors, teachers or lawyers?

It's lonely, too. Katie needs a friend, but who can she trust with her secret? That she's just a child living in her home, alone?
