Relsomorye. Vast expanses of poisoned earth covered with a network of steel rails and wooden sleepers. The tracks connecting times and countries are laid in all directions, wherever you look. They go into eternity. But there are rumors from island to island that somewhere beyond the horizon there is an exit to where there are no rails, to where Paradise is located, full of riches... And it is he, Sheamus ap Suurup, the doctor’s assistant on the Midas mole train, who finds the key to solving this mystery. But can he reach the edge of Railsea before the pirates and railfleet get to him?
