The highly anticipated fifth and final book in the bestselling Stranje House series.

When her family banishes her to Stranje House, Sera learns the importance of keeping some things secret.

At Stranje house, a school for unusual girls, Sera hides her abilities but finds friendship among the other girls who each possess remarkable talents. These outcast young women are secretly being trained to enter the perilous world of espionage, diplomacy, and war.

Conquering Europe wasn't enough; now Napoleon wants Britain. He and his band of assassins and spies, the Iron Crown, led by the ruthless Ghost, have abducted the Prince Regent. With Britain teetering on ruin, the young ladies of Stranje House must join the desperate hunt to find the Prince before it's too late. Now, more than ever, Sera's secret gifts are needed to help avert disaster. Dare she risk it?

Amid the chaos, Sera discovers the only person who truly understands her is the one man they all fear. The man set on destroying England. Can she save her homeland and her heart... from Ghost?
