Book 3
The Furnace never fails-or so the Autarchy claims.
For Lee Chungho, once a boy and now a hybrid weapon, that promise is both curse and temptation. When he discovers the serum that fuels the Furnace kills as often as it "heals," he begins to wonder: could poison undo what was forced upon him? Could death itself be a path back to humanity?
Haunted by his parents' capture, driven by Yuna's sacrifice, and burdened with protecting Ji-Eun, Chungho descends into the heart of the Furnace and Moon Hollow-the graveyard of failed experiments. What he finds there will test not only his body, but the last fragments of his soul.
The Duck That Moved Mountains is a searing tale of faith, memory, and rebellion-where salvation may be poison, and the only true freedom is choosing what to do with the weapon you've become.
