It sounds like it's the penultimate Obernewtyn update out soon - there's ANOTHER final book coming!

Have you read the Ship Who Sang series by McCaffrey? I love those.

I'm assuming you've already read Lord of the Rings and associated books. I would happily recommend the Discworld series (Terry Pratchett) to anyone - and if you like humour and literature in your fantasy, try Jasper Fford's Bookword books.

George RR Martin's Fire and Ice books may appeal, Terry Brooks has a nice series in Magic Kingdom for sale. I still like the Narnia books. Neal Stephenson's Anathem is on my bookcase for a good reason too.
