Just that, really. I'd like something that helps them develop their reading without being off putting.
To give you an idea...they can read well, but in terms of comprehension/enjoyment things like Claude and Wigglesbottom Primary are too 'easy', while Jeremy Strong, Beast Quest etc are a bit of a drag for them.
Anything in between would be great. They've just finished the Sparky at Magic School books by Ruby Nash and enjoyed those.
Thanks for any ideas.
