When a sharp cry wakes Jean, the sole midwife in Barquer's Bay, Nova Scotia, in the middle of the night, she's convinced it must have been a dream. But when the cry comes again, Jean ventures outside during a terrible tempest and is shocked by what she discovers--a young woman in labour, barely able to speak a word of English. Jean can only assume she must be Muirin, the new wife of her neighbour up the road, but when the baby arrives, Jean is only left with more questions. Why is the baby so unusual? And why is Muirin's husband so fearful of his wife and newborn son spending time by the sea? Though Jean learned long ago that she should stay out of other people's business, her growing concern--and growing feelings--for Muirin mean she can't simply set her worries aside. But when the answers she finds are more surprising than she ever could have imagined, and the truth about Muirin's mysterious behaviour reveals her marriage may not be all it seems, will Jean be able to set things right and save the woman she loves before it's too late?
