These Witches Don't Burn Book by Isabel Sterling (Author)

Hannah's a witch, but not the kind you're thinking of. She's the real deal, an Elemental with the power to control fire, earth, water, and air. But even though she lives in Salem, Massachusetts, her magic is a secret she has to keep to herself. If she's ever caught using it in front of a Reg (non-witch), she could lose it. For good. So, Hannah spends most of her time avoiding her ex-girlfriend (and fellow Elemental Witch) Veronica, hanging out with her best friend, and working at the Fly by Night Cauldron selling candles and crystals to tourists, goths, and local Wiccans.
