If books about mermaids aren’t really your thing and you’re looking for something a bit earthier, you might be interested in selkie lore. For the uninitiated, selkies come from Scottish folklore, stemming particularly from the Northern Isles of Orkney and Shetland. Selkies, a kind of mythical creature that shapeshifts from a seal to a human form. In many examples of selkie legends, part of the lore typically involves a woman selkie who loses her pelt to a man of the land. When this happens, she is tied to him so long as she is unable to find her pelt, and therefore unable to return to her seal form and her ocean habitat. These six YA books about selkies drop readers into stormy seaside towns, sparkling ocean depths, and treacherous rocky crags.
