Please help!
DS1 is 15. He is an avid reader - getting through around 12 books a week - but the teenage section in our (small) local library no longer has anything he hasn't read, and we are finding it difficult to find suitable books for him in the adult section.
He loves Terry Pratchett and has read everything he has written. As far as teenage novels are concerned, he likes Robert Muchamore, Anthony Horowitz, Eoin Colfer, Michelle Paver, Angie Sage, Derek Landy.
This sort of book is not really my style and so I am having difficulty recommending similar adult authors.
Can anyone make any suggestions please?
