I really don't know if i like this book or not. 
 I like it a lot until the chapter "stardust". I would give it 5 stars. Then the sad things happened((view spoiler)[Specifically when he left his family forever just like that. The book describes with details how much pain they have been through when he was gone, then he just leaves them forever. Just like that. What the hell!!!!!? (hide spoiler)]). 
 After finishing the book i came here and read some reviews. And now that I've read them i can't help but agree with them that the only adult content the book has is sex and violence. Otherwise it's childish. I was enjoying the book very much and it never occurred to me. But now i can't help noticing this. 
 So until the chapter "stardust" i give the book 5 stars. After that i give it 1 or maybe 2 stars. 
 I'm sure if it didn't have that part about his family that i mentioned in the spoiler i would give it a 5 star. It was a major deal breaker for me. And completely pointless.
