A worthwhile book for 7~8 grade and up. The plot is simplistic and yet it grabs you and wouldn't let you go. It's a short read though, I finished it in one sitting.
I've read this book more than 5 years ago back in high school. Until now, I still haven't found another as poignant and matter-of-fact as this one. The author was not the first one that use this format however it was still fresh at the time, but other authors have taken notice... oh well.
I wish the author would explore more (ie. write other books) in this genre but none so far.
