All We Know of Heaven — Phyllis Halldorson

Ensign Heath Tanner had spent six years a prisoner of war -- six years of private hell. Throughout, visions of his angelic wife, Michaela, had sustained him. He'd dream of one day returning home, of Michaela welcoming him with open arms....

The navy had declared him dead, and Michaela...well, she'd borne their son alone, and she'd made plans for a new life, a new marriage. Heath could still see the passion in her luscious brown eyes, but could he ever recapture the heavenly love that fate had so cruelly snatched away?
