Born Kathleen to an immigrant Irish farming family in southern Ontario, Kit McNair has been a troublesome changeling since, at ten, they fell through the river ice and drowned--only to be nursed back to life by their mother's Celtic magic. A daredevil in boy's clothes, Kit chafes at every aspect of a farmgirl's life, driving that same mother to distraction with worry about where Kit will ever fit in. When Rebekah Kromer, an elegant German-Canadian doctor's daughter, moves to town with her parents in April 1939, Rebekah has no doubt as to who 19-year-old Kit is. Soon she and Kit, and Kit's older brother, Landon, are drawn tight in a love triangle that will tear them and their families apart, and send each of them off on a separate path to war. Landon signs up for the Navy. Kit, now known as Christopher, joins the Royal Air Force, becoming a bomber navigator relied on for his luck and courage. Rebekah serves with naval intelligence in Halifax, until one more collision with Landon changes the course of her life and draws her back to the McNair farm--a place where she'd once known love. Fallen on even harder times, the McNairs welcome all the help she is able to give, and she believes she has found peace at last. Until, with the war over, Kit and Landon return home.
