   Summary

   When Violet kidnaps all fourteen grandkids for the monthly sleepover, Penelope Bridgerton decides it’s the perfect night to test-drive a ridiculous viral TikTok outfit that promises cartoon-level curves. Colin never stood a chance. One dropped dumbbell, several malfunctioning brain cells, and a whole lot of “bedroom cardio” later… maybe three kids isn’t their final number after all.
