Next read for a Pratchett loving young teen?

[Thematic]

Hi, my son has just about finished every Terry Pratchett book. He's a voracious reader and I need suggestions for his next read. He's a very mature 13 year old with a reading age more like 18, so I need exciting, funny and mildly complex books but ideally without too much sex. Probably not kids books as he's ready pretty much everything going. Doesn't have to be fantasy or sci-fi - I don't think specifically that is what he enjoyed about Pratchett, it was more the cleverness and humour. I had thought maybe some Stephen King like the Dark Tower perhaps?

Garth Nix, but not A Confusion of Princes - too old for him.

T Kingfisher’s Minor Mage but not her other books for the same reason.

Jasper Fforde The Last Dragonslayer series, though book 4 was less good.

Diana Wynne Jones, especially The Ogre Downstairs.

Douglas Adams above all :)

Notes From a Small Island was the first book that made me cry with laughter on a train. Love all his books!

Some great suggestions on here already. I’d just like to add in Day of the Triffids. At tgat age I used to pick up a lot of my DF’s books and loved some of the Tom Sharpe ones.

Oh yes, Day Of The Triffids, Midwich Cuckoos.

The Silver Sword - Ian Serraillier

Marcus Sedgwick books

Loads of good recommendations here. I'd add Chris wooding - the haunting of alaizabel Cray was excellent, and the Montmorency series by Eleanor updale.

I was thinking Gaiman, but there's quite a weird sex bit in American Gods I remember, so I was thinking maybe the adult books weren't quite suitable? He's only just 13.

Yeah but Neverwhere, Anansi's Boys, Stardust are good. Plus Good Omens.

My godson is 12 and adores all the Percy Jackson books, and other stuff Rick Riodan has done. No sex in those.

Rick Riordan is very good and the classics, The Hobbit, C.S. Lewis, Alan Garner.

Jasper Fforde - he has a similar sense of the ridiculous to Pratchett and Adams.

Ben Abramovich the Peter Grant books or Jasper Fforde the Thursday Next books. I’m a massive Terry Pratchett fan and these are some of my favourites since we lost TP!
