Our DD will be 5 in September and loves Roald Dahl. We've read The Twits, George's Marvellous Medicine, Charlie and the Chocolate Factory and Matilda. She also has Fantastic Mr Fox (read by Melvyn Bragg), The Giraffe the Pelly and Me (read by Hugh Laurie) and The Enormous Crocodile (read by Stephen Fry) on CD for car journeys and loves them all. Other loved books at the moment are the full versions of the little mermaid by H C Anderson - it is wordy, though beautifully poetic, full of Christian messages from a certain era about immortal souls etc but she adores it, possibly due to the beautiful pictures and the comforting ending. Sally Pomme Cayton's Persephone is wonderful (lovely illustrations, beautiful re-telling) and DD really enjoys that too. Clayton's Greek Myths book is quite good too (it doesn't include the Persephone and Demeter story so I got that separately).
DD likes non-fiction too so we have numerous Dinosaur and pre-historic animal books plus a few of the Children in History series by Fiona Macdonald (books on Tudors, Stuarts and Victorians) which are an easy read but are about the lives of children, so strike a chord with her. Usbourne early reader on Elizabeth 1 is very good too, again easy to read but just enough information to be useful and appeal to young children. The information kids retain from these books is amazing - DD saw a different picture in another book and said "Anne Boleyn" and "King Henry" -I had to read the print under the woman's picture to see who it was but DD was right, even though ti was a different picture of her to the one in her other book! Usbourne see inside books are also really good, DD has The Human Body and How Things Work. Would also suggest early reader or beginner books on Ancient Egypt will grab the imagination. DD is fascinated by the idea of the mummification of anyone but especially of cats.
