Awake, My Heart — Patricia Robins

What happens when a young man and a young woman, each bitterly distrustful of the opposite sex, not only meet but find themselves sharing the same country house? At first Luisa, returning home from abroad, finds herself hating Martyn Saunders, a young vet injured in the World War II. Martyn becomes engaged to Luisa's best friend, and too late he and Luisa discover their love for one another. First loyalty, then an accident, contrive to keep them apart, and when reconciliation seems likely, another woman from Martyn's past interferes, until love at last finds a solution to all their problems.
