I recommend that you read this book :)
The book is about this boy called Gerogry he did something naughty ( Im not telling you what he did because I don't want to spoil it for you :)) and there was this school camp that he went to so his dad wont tell him off after he finished from work, His mum dropped him off to school where they got on the bus, When they were there the other boy had a sign saying beware of Silas scratch it was a rumour from when his dad was there, Gerogy found out that his dad made that rumour.
I hope you read this book and yea I hope that I didn't spoil the book for you. :)
I also love reading books about diary of a wimpy kid.
