When Rayna Vance inherits her estranged father’s isolated home on Hearth Island, she expects a house to clear out. Instead, she finds a museum of obsessions: rooms of labeled sands, walls of maps charting sounds and memories, and thousands of stones. To settle the estate, she must decipher his silent language. As she learns to listen—to the island’s whispers and the stories held in polished rock—she uncovers a hidden language of profound love and loss, and a breathtaking legacy meant only for her. A hauntingly beautiful novel about grief, legacy, and the quiet, tangible ways we keep what we love.
