Okay so I am aware that this is a elementary school book, but if you just read the first book, you will read the others. These books are HILARIOUS. I am 18 years old and I have read all of the books. Personally, I don't like the movie adaptations as much because, I don't know there not as funny as the books themselves. The first book is basically about a kid named Greg Heffley's struggles in middle school. Sure its not a thriller, fantasy, or horror themed book but it is a page turner. Its just sort of a book that one sits back and reads, not one that bored you to death with the twenty ways of describing a sunset taking over 5 chapters. My rating? 10/10
