Chapter book for me to read to 9 and 7?

[FusionChefGeoff]

Tend to do classics from my childhood but drawing a blank!

Ronald Dahl
Lion Witch and Wardrobe
Secret Garden
Little princess

DS is 9 and DD is 7 - no particular cross over in interests although they both enjoyed Wimpy Kid.

What have your best chapter books been??

Dick King Smith has some goods kids books that would suit those ages.
We have enjoyed Harry's Mad, the Sheep Pig and Hodgeheg.
