Mouse House is good for quite young children - The Mousewife maybe for a bit older, I think.
DD has enjoyed The Fairy Doll aged 5 (the beginning of it is here but I was going to wait a couple of years before The Doll's House, which again is a bit more complex (and one of the dolls goes up in flames!)
talking of mice - The Church Mice by Graham Oakley is back in print. (and the sequel The Church Mice Adrift - i assume there will be more forthcoming!) that's suitable for all ages! but as a picturebook, from 4 upwards, i would say.
Jane Nissen has reprinted loads of amazing stories not touched by other publishers. Green Smoke by Rosemary Manning (the R Dragon series) here's the publisher's website they're available in most good (bricks and mortar) bookshops!
