Winner of the Blue Peter Best Book award 2015, this is a diary-style, funny story with secret plans and crazy stunts. Izzy is delighted that she has been chosen to look after new French girl, Matilde. Izzy and her friends can’t wait to show her their secret den and give her their advice on how to avoid the ‘poison’ that is school dinners. However, when they discover that Matilde actually likes school dinners, they decide that she must be some sort of spy who is after all of their secrets. This is a fun, easy read for the lower end of the age range.
