Shawna Keys has fled the world she only recently discovered she Shaped, narrowly escaping death at the hands of the Adversary who seized control of it ... and losing her only guide, Karl Yatsar, in the process. Now she finds herself alone in some other Shaper's world, where, in her first two hours she's rescued from a disintegrating island by an improbable flying machine she recognizes from Jules Verne's Robur the Conqueror, then seized from it by raiders flying tiny personal helicoptors, and finally taken to a submarine that bears a strong resemblance to Captain Nemo's Nautilus. Oh, and she's accused of being both a spy and a witch. Shawna expects - hopes! - Karl Yatsar will eventually follow her into this new steampunky realm, but exactly where and when he'll show up, she hasn't a clue. In the meantime, she has to navigate a world where two factions fanatically devoted to their respective leaders are locked in perpetual combat, figure out who the Shaper of the world is, find him or her, and obtain the secret knowledge of this world's Shaping. Then she has to somehow reconnect with Karl Yatsar, and escape to the next Shaped world in the Labyrinth ... through a Portal she has no idea how to open.
