Love It

I've already read this book, and I loved it. Ivy has some personal issues, including that she is estranged from her sister Tabitha. Tabitha can do magic, and Ivy can't. But, Ivy is a private investigator and is called to a case at the school where Tabitha teaches, so she must confront the past and figure out how well she really knows her sister.
I would describe this as a magical, emotional cozy mystery.
