My 7 year old DS (Y2) is a fluent reader and will have two chapter books on the go at once - one he reads to himself and one we read to him. Would love recommendations as I'm running out of ideas. I haven't started him on Harry Potter yet because although I think books 1 and 2 would be fine for him, the books gradually get more adult as you go through the series so I feel like he needs to be a bit older to enjoy them properly. Books he has read or been read and enjoyed include Charlotte's Web, Alice in Wonderland, The Railway Children, The Secret Garden, Tom's Midnight Garden, the Zeus the Mighty series, Beast Quest series, Sasha and the Wolf, Toto the Ninja Cat, The Worst Witch, the Narnia books, all the Roald Dahls.
The Percy Jackson books look good but wasn't sure if he was too young? Not in terms of reading ability but content - don't want the story to go over his head. Would love other recommendations!
