Este é o Engenheiro Cósmico de Clifford Simak.
Our band of three make it to Pluto where they engage the assistance of a genius scientist and a gung-ho spaceman. Contact is established with the mysterious message-senders and our party finishes up at the edge of the universe where the ‘cosmic engineers’ enlist their help to stop two universes colliding. Which of course they do, thereby saving each from total annihilation.
