This book is scaring the hell out of me
The Spook's Apprentice by Joseph Delaney. It's about a young boy who is the seventh son of a seventh son and becomes apprentice to the Spook--the old, weathered monster hunter who rids the town of boggarts, witches and things that go creepy crawly.
It has some truly scary moments and I wonder how kids perceive it. I wrote a scene not too long ago and then got rid of it because I thought it was too scary...now I'm reconsidering. I know it still has to be right for me though, and not just because someone else does it.
It's written in a very spare style, but really effective. The unnamed country is very English farming town circa late 1800s.
I highly recommend this book if you want to be creeped out. I think there are five in the series.
By the way, that cover is really cool, but I think it is the British edition. Those Brits always get the cool covers.
