The rabbit hole deepens… Against Institute regulations, Eva is allowed to celebrate Christmas Eve with her family. As a reward, she was told, but she soon finds that Cael's leniency comes with ulterior motives. Nothing knew there. Except, his grip on her life reaches further back than she dared to imagine, and he's not done playing with her. Who can she trust? Her mentor dismisses her questions, her charming chaperone leads her on a wild goose chase, and Maureen brushes her off, insisting that she should pay attention to a particularly mysterious artefact instead. In this quagmire, Eva continues to gather information to keep ahead of their games… until she stumbles onto a memory that defies reality and forces her to question everything. Even her own sanity.
