Charmed By the Past by Aimee Robinson

She’s researching her family’s genealogy, but she never expected to become history herself.

Sarah Johansson is planning a family reunion when a photo of a little-known relative sparks her curiosity. A closer look at the post-World War I image causes her to tumble back in time to 1918 and into the hospital room of a brooding, wounded infantry corporal.
Jacob Bellamy is done with war and everything it involves. After risking his life in the trenches, he hopes to finally find peace by retiring to his family’s farm. But when the war’s toll strikes too close to home and lands him in a hospital bed, the last thing he’s prepared for is the beautiful, mysterious woman who barges into his room and demands help—or the long-dead feelings she stirs inside him.
As Sarah tries to unravel clues about her family’s history, her attraction toward the sexy Army veteran only grows. But her time in the past is growing short, and when an old wartime enemy of Jacob’s sets his sights on the blond beauty, Jacob will stop at nothing to keep her safe…even if it means losing her for good.
