Margaret's whole world changes when her family moves to a cottage by the sea to be near her grandma. One evening, Margaret spots a mist over the water. No, that's not mist ... clouds, maybe? No, they're unicorns descending onto the shore! They vanish as quickly as they'd appeared, but accidentally leave behind a baby, tangled in the weeds. Margaret, lonely and in need of a friend, brings him home... A heart-warming story of friendship and kindness.
