Query: intense but a great read

When I first started reading the book, I wasn't quite sure what to make of it. It's extremely intense and I wasn't sure where the author was going with the extreme violence. I kept reading out of pure curiosity, not yet convinced that this was a work worth reading. However, once I got deeper into the story, I became so enthralled with the characters. I could not put the book down. I became hooked. I became absorbed in the lives of the characters. I continued reading, not simply out of pure curiosity, but out of a need to find out that the character's turned out alright. I had to know what was to become of them.Now, I'd recommend this book to anyone.
