The story follows three women whose lives intersect through a white cat named Mimi:
A septuagenarian widow who decides to revisit Ischia, Italy—a place where she was once very happy with her late husband.
Susann's young neighbor and a school teacher. Despite knowing nothing about cats, she agrees to watch Mimi for three weeks.
Leonie's best friend who has recently inherited a vast collection of books and opened a café called "La Señorita Paula".
