In The JerryMaya Summer Holiday books there are lots of fun activity tips that will last all summer long. Test your knowledge about Valleby, where Jerry and Maya live, in an ingenious quiz, or concoct secret messages, draw pictures, write descriptions of your friends and take their fingerprints, and lots more. Need to take a break? Relax with a glass of lemonade and a home-made bun! Recipe courtesy of the Valleby Cafe.

JerryMaya’s Summer Holiday Book: The Detective Challenge also contains a newly written story by Martin Widmark. It’s the day before the summer holidays and headmistress Gun has invited the vicar, Barbro Palm, and the police inspector to talk about what it was like when they were young. But the speakers have been a bit sneaky; they have all snuck in a little lie in their stories… Can you uncover the untruth before Jerry, Maya and the other children do?
