Wicked Chill (Away From Whipplethorn Book Four)

Matilda Whipplethorn is feeling very unlucky. It’s only because she is. Matilda got the family to Vienna, but no farther. Her parents are missing in action, so she’s in charge. Now she’s hiding in plain sight. Plain sight means being a maid in St. Stephen’s Cathedral, battling tiny trolls, and avoiding a certain valet.
