The Secrets of Sam and Sam

Susie Day grew up in Penarth, Wales, with a lisp and a really unfortunate choice of first name.

She has had lots of jobs, including guiding tourists and professional nappy-changing - but she always wanted to be a writer. Her first book, Whump! in which Bill falls 632 miles down a manhole, won the BBC Talent Children's fiction prize, and was published in 2004.

Susie now lives in Oxford, England, and eats a lot of cake and drinks a lot of tea.
