Whatever you do, don't ask Greg about his summer vacation because he definitely doesn't want to talk about it . . .

It's a brand-new year and a brand-new journal and Greg is keen to put the humiliating (and secret!) events of last summer firmly behind him.

But someone knows everything - someone whose job it is to most definitely not keep anything embarrassing of Greg's private - his big brother, Rodrick. How can Greg make it through this new school year with his not-quite-cool reputation intact?
