After three decades of marriage, Jo catches her husband in bed with a much younger woman. To add insult to injury, her anger makes the magical powers she had repressed at puberty abruptly flare to life. She has to learn to control the magic while holding down a full-time job and going through a divorce.

Jo is lucky in that her best friends are both witches and are able to help her learn about these new-found abilities. While waiting for the divorce to finalize, and under the tutelage of her BFFs, she discovers she's a good magical potion-maker.

When her boss decides to retire, Jo not only takes her potion business full time but makes a move to a cabin in the mountains. More surprises await her there: she has a familiar - a snarky crow named Esme; and her neighbor, another fifty-something single woman, can speak with animals.

All is not bliss, however. Jo is accused of murdering a woman she has never met, and the investigator assigned to the case refuses to listen to reason. It's up to her to prove her innocence and bring the investigator to his senses. Can magic help her?
