A secret, underground railway. A city, hidden behind a wall. And a creature who walks out of the water... But that's not all. A pack of killer dogs, on the loose in a drowned city. A girl of indeterminate age, reading minds and dreaming the future. And boy on a quest who makes the most unlikely of bonds... In the third part of Guy A Johnson's dark, dystopian thriller, connections are made and secrets revealed that were better left undisclosed. And as the truth about the authorities is finally uncovered - the past and the present - plans are set in motion to right the wrongs. Plans to break down impenetrable barriers. Plans to liberate the impoverished. Plans, once started, that cannot be stopped...
