Scary books for a 9 year old

[crazygracieuk]

I'm after some scary books for my ds who is 10 in March and a reluctant but very competent reader. He's just read the Graveyard Book and the first two Hardy Boys. The only scary books that I've read were things like Stephen King so I could really do with a more suitable selection that are fictional or factual.

My DS is 8 and likes scary books and things with monsters in at the moment. He liked:

Harry Potter (later ones are more scary)
Percy Jackson series (less childish than the early HPs)
Spooks Apprentice series
He's also read a couple of Beast Quest series.

Try Groosham Grange and Granny, both by Anthony Horowitz. Good, straightforward reads with a good blend of horror and humour. Would appeal to a reluctant reader, I would say.

Grinny by Nicholas Fisk is horrid.

Will think of more tomorrow.

Thank you for replying everyone. If you think of any more, let me know.

OOOOOOOOH love the Grinny thanks for the reminder.
