Eleven-year-old Aran has never truly fit in with his selkie clan. Aran was born in his human form, without a pelt to transform him into a sleek, strong seal. Each day he waits, left behind while his selkie family explores the deep ocean. But when Aran discovers he is only half-selkie, with a human father, he begins to worry that his pelt will never come. His mother, refusing to give up on Aran s true form, sets off with the rest of their clan to find the wise selkies far to the north who might have the only solution to Aran s problem.
