I really enjoyed the first 50 or so pages of this book, the descriptions given for the kids was wonderful (ok I hated Theo), and I really looked forward to the book. But when they got to that (in)famous school of fear the book took a turn and changed for me to boring no thank you. Also my dislike for Theo just kept growing. Really he kept whining and complaining.
Also the pictures were nice, but looked kinda weird and scary on my ereader. Most of the times it looked like the kids had no pupils. :\
