Everyone knows you should always say sorry when you make a mistake. But when Clare forgets this very important rule (OOPS!), things spiral wildly out of control...

Suddenly, the consequences are bigger, bolder and stranger than Clare could ever have imagined - with dragons, trolls, polar explorers and a whole flotilla of extremely furious fishermen standing between her and putting things right. A riotous, fast-paced adventure that proves one small word can make a very big difference, this is the perfect picture book for sparking laughter, conversations and repeat reads.
