Doppelgangster by Laura Resnick
Esther Diamond is a struggling actress in New York, who is working as a waitress in a mob restaurant to pay the rent. Then she witnesses a murder to the dismay of her cop boyfriend Connor Lopez. Weirdness is afoot on the streets of New York, so Esther and her magician friend Max and a friendly elderly hitman work to stop a magically induced mob war. This is a good fun urban fantasy. There are a few too many exposition dumps but one can overlook that.
