“When my mum was still living, she used to tell me the most vivid stories,” Adaira began. “Stories about the spirits, about the folk of the earth and the water. I enjoyed her tales and held them close to my heart, but I never thought too deeply about them. Not until after she had died and my father fell ill and I realized I was about to be alone, the last of my blood. Not until Eliza Elliott went missing.

“Torin and I both went to my father, to seek his advice. For it was evident to us that someone in the clan must have done something to upset the spirits, and the folk had taken one of our own to punish us for it. My father instructed Torin to continue searching the east with his mortal strength—his eyes and his ears and his hands, to be ready at any moment for a spirit portal to open and lead him to the other side. But after Torin was dismissed, my da spoke to me alone. He asked me to recount one of my mum’s stories, the legend of Lady Ream of the Sea, which my mum often sang to us in the hall.

“So I did, although I hadn’t thought of my mum’s stories in years, for the pain they bring me. And yet even as I thought of Ream rising from the foam of the tides, I still didn’t grasp what my father was hoping I would understand on my own. It took me a few more stories before I saw it.”

She paused. Jack was transfixed. “And what was that, Adaira?”

“That in my mum’s stories and songs . . . she could describe the spirits in perfect detail. How they looked in appearance. How their voices sounded. How they moved and danced. As if she had seen them manifested.”

Jack instantly thought of the woman in the sea, how her hair had tickled his face. He shivered. “And had she?”

“Yes,” Adaira whispered. “It was something only she and my father knew. A bard can draw the spirits in their manifested forms, but only with a harp and their mortal voice. Old knowledge passed down on the isle for many years, kept hidden by the laird and bard out of respect for the folk.”

“Why would your mother need to sing for them?” Jack said, his palms beginning to perspire.

“I asked my father this very question, and he told me that it was a way to ensure our survival in the east. We remained in good favor with the spirits, he said, because her worship pleased them, and they in turn ensured that our crops grew twofold, and the water ran clean from the mountains into the lochs, and the fire always burned through the darkest and coldest of nights, and the wind didn’t carry our words over the clan line to our enemies.”
