Dear Prudence is Slate's advice column. Submit questions here. Dear Prudence, I just found out something horrible about my friend. Her dad is her mom's son. That is, she is a product of incest. She casually mentioned it one day when we were at book club. Do I break off her friendship? She is lovely and has kids of her own with a lovely man, whom my husband and I are friends with. -Not Loving the Lineage
Prime Video; available now Waleed Zuaiter, Robin Wright and Laurie Davidson in The Girlfriend. Photograph: Christopher Raphael/Courtesy of Prime Summed up in a sentence A steamy, incestuous adaptation of an excellent novel that pits an adult son's new girlfriend against his mother in an ever-more extreme contest. It has lost little of the book's psychological acuity and retained all of the suspense. Not one to watch with your sons, perhaps, but otherwise enjoy.
