Aoife searches for magic everywhere—in her books, in herself, and especially in the waters that surround her home on the Arranmore Islands of Ireland. The lore of the Selkies tells of half-human, half-seal creatures kidnapped off the shores and forced into marriage and child rearing and haunts Aoife as she reads one story over and over. A single discovery about her distant and single mother’s mysterious past is all it takes to send Aoife spiraling on a journey to find the truth about her mother, the Selkies, and the existence of magic.
