Forsake the world that hates you. Embrace its monster.

Tresor Institute accepts only the worthy, and Ada Călinescu is anything but. Intractable, mannish, a child of convicted terrorists, she can at best hope to be overlooked. Yet somehow the Institute accepts her application for transfer. Her ticket to the polar town of Heilung, home of the Institute, arrives free of charge.

Her only chance to forge a brighter future.

Except Heilung welcomes Ada with news of a brutal murder. Militiamen stalk the town, keen to fill their arrest quotas—and Ada knows she could make an easy scapegoat. At every turn the bloody conspiracy follows her, from the halls of Tresor to the arms of a stranger she yearns to make hers. What starts as a dalliance risks putting Ada at odds with the Bureau itself.

And then expulsion will be the least of her concerns.
