Ds1 is nearly 7, is a very capable reader but is not that keen on reading alone. I need to find him some decent, accessible, imaginative chapter books that are not too long, preferably about ordinary kids having 'adventures'. He has read the first 4 books in the "magic tree house" series and really enjoyed them but has stalled now so needs some variety.
My local library consists of about 3 shelves of Rainbow Fairies books 
, a few (to me) soppy-looking books about animals, and an assortment of negative and patronising books clearly aimed at boys e.g. Horrid Henry, Dirty Bertie, Captain Underpants etc. 
We have tried Beast Quest/Dinosaur Cove but ds1 finds the unusual names of dinosaurs and beasts etc confusing.
Oh, and I tried Waterstones and WH Smith and it was basically the same things. Also had a look on Amazon but unless you know what you are looking for it is pretty time consuming.
Find it very frustrating actually. I was into Secret Seven at his age but had hoped to find something more up to date (I.e. with less dodgy "circus-folk" etc).... To coin a phrase, am I being unreasonable?? Any recommendations??
