The Sea Before Us (Sunrise at Normandy, #1)

In 1944, American naval officer Lt. Wyatt Paxton arrives in London to prepare for the Allied invasion of France. He works closely with Dorothy Fairfax, a "Wren" in the Women's Royal Naval Service (WRNS), who pieces together reconnaissance photographs with holiday snapshots of France—including those of her own family's summer home—in order to create accurate maps of Normandy. Maps that Wyatt turns into naval bombardment plans for D-day.

As the two spend time together in the pressure cooker of war, their deepening friendship threatens to turn into something more. But both of them have too much to lose to give in to love . . .
