This has been sat on my shelf for ages and I haven't picked it up as I didn't know what I would think of it. I'd give it somewhere between 2/2.5 stars. It was enjoyable but nothing amazing and I enjoyed the thought of Diyu. The writing style was very very simple. I know this is a Young Adult book but the writing seemed a lot more 'jeuvenile' (don't know if that's really the right word) than other books I have read in this genre. I may give others on this series a go but won't rush.
