Mouse is doing his best to stay out of trouble. Cat is doing her best to land herself in it. They've both had it pretty tough so when they meet by chance they thank their lucky stars.

Weird and wonderful things happen when they're together - but how long can it last? Because everyone has their secrets - and there can be only one winner in a game of cat and mouse.

Can't there? Cathy Cassidy's hugely engaging writing has massive appeal for 8-13 year olds.

Cathy's last book, "Sundae Girl", spent six weeks in the Bookscan top ten.
