I didn't particularly enjoy this book, by the end I was finding it even more unbelievable and repetitious.
We meet 5 children, Robert, Anthea, Cyril, Jane and their baby brother nick named The Lamb, who are moving the a big white house in the country with their mother. Whilst out exploring one day they find a sand fairy in the gravel quarry, when they realise that the sand fairy grants wishes they think they are in for many happy adventures. However, not all wish are as good as they seem when they think of them and they get what they wish for.
