Valentine's Day is right around the corner, but neither Samantha nor Kathy are feeling in the mood lately. Samantha and Steven have been arguing about where to live while Kathy has been awkwardly reuniting with her ex-boyfriend Jeremy, who might also be dating someone else. Scarlett, an enchantress, tracks Kathy down at work for help saving her lover from an evil witch who put him in a spell that Scarlett is unable to break with her own magic. The witches lean in to the distractions from their personal lives and are ready to travel to Buffalo to help Scarlett reunite with her lover. Except, Steven and Jeremy insist on coming along for the weekend, drudging up all of their issues that they'd rather escape from. Worse, Jeremy still doesn't know that they're witches. What could go wrong? is the sixth book in the Coven series, which serves as a prequel series to the Under the Moon series.
