Plot summary
The book begins with Jiggs in the inner world discovering that Drake is still alive, but has been affected by the nuclear radiation from the explosion at the end of Spiral. He also finds the burnt body of Rebecca One lying near Drake. Jiggs rescues Drake and carries him to the Topsoil. At the same time, Elliott and Will are trapped in the inner world, in the destroyed city of New Germania. They meet three New Germanians who have survived the virus released in the inner world and, along with them and a Bushman called Woody, they go to explore one of the Pyramids from the jungle. Also, they find out that the Bushmen are part Styx (because they speak the Styx language at a much higher pitch). After they get into the Pyramid, something unexpected happens as Elliott touches a trident sign (like the ones that Dr. Burrows and Will found on their first exploration of the Pyramid). The Pyramid vanishes into thin air and an enormous tower appears out of nowhere in the jungle. Elliott senses that there is something missing from the tower, then she and Will find out that at the top of the tower there is a portal to Topsoil, and so they teleport themselves to London.
Meanwhile, Chester is Topsoil with Stephanie, Old Wilkie, and Parry. Still grieving over the deaths of his parents during Professor Danforth's betrayal in the previous book, he discovers that Parry is still allied with Danforth and the death of his parents was being part of a plan. He then runs away from the others with Martha.
