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. She could fall in love with the snowy cobbled streets and a surprising musician, but the revolution in France is making its way into Austria and the Viennese fairies are panicking. Matilda might change the course of history if only she could use the power she’s been forced to hide.
