The Kelpie's Pearls, by Mollie Hunter

A beautiful tale set in the Scottish Highlands. An old woman helps
a kelpie who's foot was stuck in some rocks. They quickly become
friends and the kelpie gifts her with a string of pearls. However a
sharp eyed trapper notices and becomes determined to get the
kelpie's pearls.

I really liked this book, the characters were interesting and the
writing very nice. It is a children's book though and a wee bit
simple in plot.
