Five Children and It by E. Nesbit. Like Nesbit's Railway Children, the story begins when a group of children move from London to the countryside of Kent. While playing in a gravel pit soon after the move, they uncover a rather grumpy, ugly and occasionally malevolent sand-fairy known as the Psammead who is compelled to grant one wish of theirs per day. Five Children and It by E. Nesbit summary from Wikipedia. Read by LibriVox volunteers.
