him to the Deeps to fend for himself. Will refuses to abandon his friend, and Uncle Tam formulates a plan for him to rescue Chester and to take him back to the surface. Will and Cal attempt to rescue Chester before he is sent to the deeps on the 'Miner's Train', but the Styx arrive and they are forced to leave Chester behind. During the botched escape attempt, it is revealed that Rebecca, Will's adoptive sister, is actually a Styx implanted in his family to monitor him. The boys head through a series of tunnels to the Eternal City, an old stone city, estimated by Will to be from Roman times, where the air is filled with deadly bio-toxins. They avoid the Styx soldiers, who patrol the city with their vicious stalker attack dogs, and eventually emerge on the bank of the Thames. Will makes for his home in Highfield, but there Will's health deteriorates, so Cal helps him to his Auntie Jean's flat where he recovers. Soon they return underground to find Will's adoptive father and attempt to rescue Chester once again. They encounter another Styx patrol, and Uncle Tam kills a member of the Styx, whom he calls Crawfly, but is mortally wounded in the fight, and the strong-willed Uncle Tam chooses to stay behind to give the boys time to escape. With the help of Imago Freebone, a member of Uncle Tam's gang, Will and Cal escape to a small hiding place halfway between the Colony and the Eternal City. There, they rest and mourn for Uncle Tam; and are told by Imago that Chester's train to the deeps will pass directly under their hiding spot shortly. They jump down into the train through a hole in the floor of the hiding spot and find Chester. Together they ride down to the Deeps. In the book's epilogue, Rebecca kills Imago, who was hiding on the surface, by poison.
