Review for Ghost Knight (read 2012):
To start with the practical aspects, the book is just over 300 pages, but the text is quite large. The chapters average at around 10 pages, and there are line drawings at various places throughout. There is some threat from the ghosts, but it's not particularly scary or gory. I would expect this to be a good transition book, for those moving from illustrated children's books, to longer, more grown up books. It has enough to appeal to some older readers, but it does have a more childish feel to it than some others I've read.
The story is about Jon, who's sent off to boarding school, something he blames on his mum's boyfriend. Once there, he immediately starts to have problems with ghosts who wish him harm, and that turns out to be because of his family history.
Jon meets Ella, a fellow pupil, who has a good knowledge of the area and of the ghosts, and with the help of her gran, she starts to help him.
The history aspects are good, and I like the implication that ghosts aren't always cute floaty characters, but can actually cause harm. It certainly has it's place, but for me, it didn't quite work as well as it should, and I do prefer Cornelia's Funke's writing for older ages.
