Warmongers and Wands by Debra Dunbar

Bronwyn Perkins has given up on love. She’s got a great job as a welder and a farrier for centaurs, unicorns and satyrs. She’s got a close-knit family of six sisters, all of them witches in the town of Accident. In her spare time, she enchants objects and creates art from metal. It’s a fulfilling life. She doesn’t need love, maybe just a cat. Or two. Or three. Nope, she doesn’t need love at all.
But a mishap on a mountain road, is about to bring Bronwyn everything she’s always wanted—everything she’s been afraid to hope for. All she needs to do is go over a cliff and down into the woods.
