Slivering Curse by D.D. Croix

A FAYTE GUARDIAN HERO. A FIENDISH ENEMY. DEADLY SECRETS THAT WON’T STAY BURIED.

After rescuing Queen Victoria from a dark fae, Jane has settled comfortably into her new life as a Fayte Guardian, working as a maid in the royal kitchen while standing ready to protect the sovereign from any worldly—and otherworldly—threats. She finally has friends, a purpose, and a promising romance. But when she visits Balmoral Castle in Scotland’s misty hills, she discovers the battle she thought she won isn’t over at all.
Something evil lurks in the heart of the Fayte stronghold, and when she investigates, she’s drawn into a conspiracy that threatens everyone and everything she holds dear. Left wounded and on the run, she doesn’t know who she can trust—old friends, new friends, even her peculiar dragonfly friend.
To find the strength to fight an enemy that knows her better than she knows herself, Jane must master new supernatural powers and dig into the past she can’t remember for answers to questions she doesn’t want to face.
Can Jane defeat the Fayte Guardians’ most dangerous foe before he destroys her, the Queen, and the Order itself?
