"I have so many super-amazing and IMPORTANT things to write about! I'll tell you all about them: I've got a brand-new bedroom-yay! My best friend Lucy moved away last week and I really miss her. I'm planning LOTS of cool inventions (I'm pretty sure some will work too!) Someone keeps sneaking into my room but I DON'T KNOW WHO! There's a new girl at school called Matilda. She looks fun but why does she act so mysteriously all the time??? I'm going to find out exactly what's going on!" -- Back cover.
