I was entertained. The book is a highly fictionalized autobiography, made up of little vignettes. Some of it might be true, most of it is probably lies and exaggeration.
I originally believed everything I read in the book, but after a discussion about it with my girlfriend I started to notice all the little things (and big things) that couldn't possibly be true.
All that said, it's a highly interesting book, and entertaining too. It's like being told an autobiography from the view of a kid as the kid is living through. None of it is quite a lie, just too fantastical to be quite real, like a child telling you it's fanciful view of yesterday happenings.
Highly recommended, but it might not be to everyone's tastes
