Sam likes being a twin. He likes having two mums. He likes cheese sandwiches and his dog and drawing comics with his friend Pea. He does not like humus - or heights . . .
His twin sister Sammie likes being a twin too. She knows that she's perfect best friend material for somebody - the girls in her class just haven't realised yet. And she knows that she's the best Sam - Sam A.
Both Sam and Sammie - and everybody in their lives seems to be keeping secrets - which ones will come out?
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.
