I absolutely love this story! George MacDonald has a lovely sort of grandfatherly style, and this is perfect to be divided up as a series of bedtime stories. A boy who has never seen night and a girl who has never seen day help each other cope with their fears. It is available online if you don't mind digging a little. Otherwise, you'll have to wait for them to find it for you. E-mail me if you want the address for the online e-text version. It doesn't quite have the charm of an actual book, but if it's all you've got, it's better than nothing.
