I've ready many YA or Young Adult novels, and they always leave me less than satisfied.The characters in those other books seem immature and the story way too dramatic. This book is unbelievably good. The dialogue between the characters is very real and the story was well written and fully developed.The subject matter is a little heavy, but dealt with beautifully and realistically. This book stayed with me long after I finished it. It has to be one of my favorite books of all time (and I'm old). I would recommend this to anyone who wants a good read. 

Question: How is it dialogue?
Answer: good
