It's been years since Coraline defeated the evil Other Mother, and Coraline died a year ago. But what happens if (Periwinkle) with her little sister (Angel) have met a old friend named: (Zexal) they haven't seen for 5 years??? Periwinkle is 11 years old, Angel is 8, and Zexal is 10 years old, and all 3 of them are close friends since childhood.
