Galway, 1820s. A young woman follows an ancient call-into the sea, into the Otherworld, and into herself. Morrigan Lane has always felt the pull of something beyond the life her village has mapped out for her. She dreams of captaining boats on the wild Atlantic, of breaking free from the fierce expectations placed on women in 1820s Ireland. But when a haunting vision of the Irish sea god Manannán mac Lir draws her toward the water one dark night, Morrigan's restlessness becomes something far older and stranger than ambition. Tracing the path of her great-grandmother through Celtic tradition, family secrets, and the shifting boundary between myth and memory, Morrigan discovers that her gifts of healing are not only real-they are needed. And claiming them will cost her everything she thought she wanted. Structured around the phases of the moon, A Moon in All Things weaves historical fiction, Celtic mythology, and magical realism into a lyrical, atmospheric novel about love, courage, and one woman's awakening in a landscape where the Otherworld is never far. 2025 IAN Book of the Year Awards, Finalist For fans of The Frozen River, Outlander, and the novels of Alice Hoffman and Joanne Harris.
