There is not much of a plot in this book, it is different parts of Greg Heffley's life.
Some parts build up and then move on to a different day. Basically every day is a new adventure for Greg Heffley.
The best part of the book is all the cartoons. The book is half writing and half cartoon.
The cartoons are drawn very well and look funny. The whole book itself is very funny.
There are no real weak bits in this book, but it is more of a book for boy more than girls.
The part in this book that is unputdownable is all of it! Right from the beginning it's great.
It is a very easy book to read and if you wanted to you could read it all in a night.
