Query: Pretty Interesting

I came across this book at a used library book sale and purchased it for trading but ended up reading it because of the reviews here. The book held my interest all the way through. I found myself wanting to get back to it in between reading sessions. I found the ending to be a bit anti-climactic and was a bit disappointed with it. I thought because the rest of the book was quite good that the ending would be better.
