she might also like the Laura's Star early reader ones (erm Secret Pony, New Teacher, Sleepover and Best Friends Forever I think they are called - they are 64 pages each I think)
My daughter likes Rainbow Fairies but she would read say one of those, then a Magic Molly, then a picture story book, then something else, then another Rainbow Fairy one.
other early reader type ones which have been popular in our house are The Lighthouse Keeper (now also available as early reader type chapter books), Animals in School by Julia Donaldson, The Kitten with No Name by Vivian French, The Witches Dog - Frank Rodgers, Usborne Young Reading books, The Troublesome Tooth Fairy, Dogbird, Dog on a Broomstick, Snowdog and Happy Mouseday.
I would probably suggest starting with the early reader type ones which are generally about 64 pages long and still have colour pictures in a lot of them. Long enough that they feel more like a chapter book and chapter book sized but with only 4ish chapters so not too daunting. Then Magic Molly ones are 80odd pages so extend a bit further and then you get ones in the 90pages, 120 pages and then up to over 200 pages. My daughter would panic at the thought of some of the much longer ones.
I have just ordered her a set of Jill Tomlinson books (Owl who was afraid of the dark, The Cat who wanted to go home etc) which seem to be 96ish pages each so about right for her. She is in Yr1.
