Query: It's Up To You

I must start this review by saying that this is my favourite book ever. You can read it just as a simple story about a man that kills another in a stupid way. There are great chances of you to enjoy it. But you can also read it as a story of a man in an absurd world...the same world we live in. I recommend for anyone who reads this book to re-read it. And again. And again. The more you read it, the stronger it is.
