Visiting his sister Mary at the lighthouse should be a delightful vacation for Elliot—except he’s going there in disgrace while he awaits his fate from the wizard council. Mary’s assistant, Rue, is a gentle, self-possessed young man about Elliot’s age. Elliot is drawn to him, and his magic seems to calm down around the handsome and mysterious Rue. Elliot sinks gratefully into the unexpected grace of Rue's kindness and friendship. He doesn’t understand why his magic is broken or why it feels whole again around Rue. But right now he’s just trying to survive, grateful for the reprieve Rue’s friendship provides. But then a a potential tragedy on the beach culminates in Rue revealing his true nature: he’s a selkie, both man and seal, with a magic that somehow complements and heals Elliot’s when they’re together. And that might not be possible for much longer.
