Birds of War — Jane Toombs

Francis and Eileen, lovers torn apart by the fortunes of war, are passionately united in Paris. Their illicit romance is threatened when her brother, Martin, discovers their secret. Though comrades in the sky, Martin becomes a bitter enemy of Francis on the ground.

Jerome, Francis' and Martin's business partner, is jealous of Francis' flying prowess and his success with women and becomes his rival, leading to conflict between the three Americans.

Love of flying unites them, the love of women divides them. Yet the fortunes of war bring them together in a way they never imagined.
