Zizou Corder is Louisa Young and Isabel Adomakoh Young, whose names are too long to fit on the front of a book.

Louisa is a grown-up and has written five grown-up books; Isabel is a kid and has written mostly schoolwork.

The original Zizou is Isabel's lizard, only he spells it Zizu. They have written four books together: the highly acclaimed Lionboy trilogy and their new novel is called Lee Raven Boy Thief.

They live in London. Only one goes to school.
