Spellbreaker

Elsie is an unlicensed spellbreaker in an alternate Victorian England, quietly undoing the aristocracy's enchantments for a secret group called the Cowls. When the wizard Bacchus Kelsey catches her at it, she buys his silence by fixing the unruly spells on his estate, while wizards keep turning up murdered and their spellbooks stolen. Slow burn, no spice, cliffhanger.
