Abook summary for diary of a wimpy kid

Greg Heffley must survive middle school while dealing with his two annoying brothers. At least he has his best friend, Rowley Jefferson, but his behaviour can be intolerable, so the friendship may not last. 

This is what it says on the back of the book if it helps...

It's a new school year, and Greg Heffley finds himself thrust into middle school, where undersized weaklings share the hallways with kids who are taller, meaner, and already shaving.
