My Husband Stole My Kidney,Then Died for the Girl Who Was Me

From the back cover

Fern Fox has spent seven years adored by her husband, Benedict James, the Chief of Surgery who treats her like glass. Then a post appears in her feed: a man asking how to make his wife donate a kidney to his dying mistress. When Benedict walks in and tells Fern she has kidney failure and that a kind college student has volunteered to save her, she recognises the post as his.

He plans to operate himself, and he refuses to let her meet the donor. Fern follows him to an upscale complex and sees the girl throw herself into his arms. The face stops her cold, and everything clicks into place.

She gathers her parents, her mother-in-law and her sister-in-law, and shows them the photo. Their certainty collapses into despair and pity, as though they are looking at someone already dead. When Benedict returns with roasted chestnuts, everyone knows he is lying, and no one says a word.
