Fab books for an 8 year old bookworm?

[Paxdora]

Could anyone recommend some good books for an 8 year old boy who has a reading age of 10.4 ?

Thanks.

My 8 yo has just devoured these and loved them. He has declared them better than Harry Potter and is now reading them for the second time.

Has he read the Percy Jackson books by rick Riorden. My ten year old boy loved them.

My DS is a bit older - 9, nearly 10 - and is also a bookworm. Over the past year or so he has been reading the Ranger's Apprentice series (by John Flanagan) and is currently reading the Alex Rider books (think they're by Anthony Horowitz).

Lemony Snicket(13 books);The Hobbit;Percy Jackson series (fantastic!)A Wrinkle in Time by Madeleine L'Engle; anything by Cornelia Funke; and of course I'm sure he's already read Roald Dahl etc.

There are so many great books out there for this age group, I'm sure someone else can add lots to my little list.

Anything by David Walliams.

Diary of a wimpy kid books are great too.

I second David Walliams.

Perhaps the Tom Gates ones by Liz Pichon?

The land of green ginger
Fattypuffs and thinifers
The phantom tollbooth
The graveyard book (Neil gamin)
Terry pratchetts discworld has done books for young adults the tiffany aching ones and the amazing Maurice and his educated rodents
Molesworth

If he's an adventurous sort of boy, I think he'd love 'My Side of the Mountain' by Jean George. You can find it on Amazon. I bought it for the boy next door's birthday a couple of months ago :)

second Ranger's Apprentice; Edge chronicles; Joshua Mowll series which starts with Operation Red Jericho; Biggles (v old fashioned, but ds1 is loving them; Chronicles of Prydain.; Jenny Nimmo

Cressida Cowell's Hiccup Horrendous Haddock series - they start off quite simple but get darker and more complex. There are 10 so far.

Susan Cooped's The Dark is Rising series.
Angie Sage's Septimus Heap series.

The how to train your dragon books.
Asterix

Great suggestions - thanks everyone

I third David Walliams my 8 year old ds has read them twice over he loves them so much
