Frankie knows she’s not like anyone else in her class: she’s different, but she can’t quite figure out why. Is it the new freckle on her nose, or the fact she’s small for her age? Or that she must go to the hospital sometimes? Everyone else seems to think she’s weird too, and they make fun of her at school.

Frankie’s dad left when she was a baby – maybe he was different too? It would explain why she always feels like an alien. So, she and her best friend Sam, embark on a mission to track him down.
