A Wife To Remember: Harlequin comics

Her estranged husband has amnesia. She knows the devastating truth that drove them apart. Should she tell him?
After Amy receives a call from her sister-in-law about her estranged husband Michael’s car accident, she returns to his side to take care of him—and help him through his amnesia. He doesn’t remember a thing, including the tragedy that caused him and Amy to separate.

Amy feels torn between Michael’s renewed cheerfulness and his lost memories. If his memories return, so will the unbearable despair and loneliness that tore them apart in the first place.
