He is just finishing off Harry Potter and loves them. We have percy jackson lined up next but I don't know what to recommend beyond this. A lot of what he wants to read may be a bit old for him (Magisterium series, Cirque du Freak, Skulduggery pleasant).
He has previously enjoyed reading the Spiderwick Chronicles, some of the Narnia books, the Scarlet and Ivy books, Knitbone pepper, all the Goosebumps books and the Bolds. He's read some Roald Dahl - liked the witches, BFG and Matilda the best. He did not finish the two Beastquest books (dull and boring), didn't like the the Grunts or Mr Gum or David Walliams.
Any ideas
