Enchanted Autumn by Ursula Klein

When Dr. Elizabeth Cowrie shows up in Salem, Massachusetts, to study the witch trials, Hazel and her best friend, Roxy, are both instantly attracted to the workaholic professor. Roxy snags a date with Elizabeth first, but when their chemistry fizzles out, Hazel sees an opportunity to pursue Elizabeth herself—until she realizes Elizabeth is avowedly anti-magic.

That’s definitely a problem since Hazel is a bona fide witch: rides a broom, has a black cat, brews love potions, lives in a haunted house, and has a vampire ex-girlfriend. Roxy is the only person who knows the truth, and Hazel has gotten used to hiding who she is, but she can’t live a lie with the person she loves most. Can Hazel give up magic to make it work with Elizabeth? Or will she give up on the love of her life instead?
