Stalked by foes and dogged by betrayal, Princess Thera is pursued across a continent vaster than she could ever have imagined, to the hidden valleys of the World's Edge Mountains, into the barrows and subterranean halls of the City of Ghosts, across the ice floes of the far north. She breached the Wall of Storms intent on taking war to the Lyucu homelands, but how do you conquer the unconquerable? The conclusion to Ken Liu's chronicle of the Dandelion Dynasty.
