The other mistress

Williams (The Wife Before, 2022) returns with another original and surprising thriller. Potential readers should pay attention to the trigger warnings Williams notes. Adira is a successful and wealthy businesswoman, but she has a big problem. Her husband, Gabriel, has been cheating. After following him, she's witnessed his indiscretions, but she hasn't figured out what to do about them yet. Then she meets Jocelyn, a sophisticated bar owner who has also been sleeping with Gabriel. Worse, Gabriel doesn't even seem to notice Adira's rage. When Jocelyn offers to help Adira take revenge on her husband, Adira is skeptical but grateful for any support she can get. The women learn more about each other while taking their spying to the next level. Soon, the idea of murder has passed through both of their minds--but will they go that far? Dovetailed in between are short vignettes from someone's past that remain a mystery until the end. Fans of The Wife between Us (2018), by Greer Hendricks and Sarah Pekkanen, won't be able to put this one down.
