Stella's mum and step-dad have gone off on holiday and have dumped Stella at the Evergreen Holiday Camp.

She's not happy! Especially when she finds out she's expected to learn to swim - the one thing her mum promised she wouldn't have to do.

She's determined not to enjoy herself and settles down for a nightmare summer, but in the end she finds herself making friends, getting into scrapes, and having much more of a good time than she ever could have imagined!
