It's the story of a 7year old school boy. He appears a lovely polite schoolboy at first but then when he starts to sing, strange things happen. Some even dangerous and people start to die.
The book is very fast fetched and quite weird in places, but strangely enough I actually enjoyed it, even though it isn't normally a book that I would choose to read. It's a very fast read and I read it in a day.
I'd recommend it to fantasy fiction buffs as a gap filler.
