So the main character is 50, but hasn’t aged since she turned 25. She lives with her parents (who haven’t aged much since their 50’s I think, thanks to a special potion) and her sister (who also takes the potion) whom she also shares a room with. Neither sister is in a relationship or has moved out and they literally fight like children. Literally sticking tongues out and mimicking. HOW is this book popular??
