I loved The Shadow Thieves. I really liked the humorous style of writing used and it was never boring, with constant action and no floods of detail that make you want to skip the two page long paragraph. I stayed up until four in the morning finishing this book and I don't regret a second of it! The only issue is that it is very similar to Percy Jackson and the Olympians - maybe a little bit too similar for comfort. All the same, I highly recommend this book and I can't wait to read the next one!
