Magic for Liars by Sarah Gailey
Here is a fun novel set in the east. Sisters who are very different, one has magic talents, her name is (oh yes it is) Tabitha, and Ivy who is a private detective. Ivy is asked to solve a murder that takes place at the Academy for Mages where Tabitha works as a teacher. All sorts of magic happens and even a budding romance in the ensuing investigation where a number of people are under suspicion. Just enjoy -- I did.
