The action of the novel is placed fifteen billion years into the future, in an era when the expansion of the Universe has given way to compression, when the sky is ablaze with the light of stars falling on each other, and only the long-extinguished sun creeps in a dark circle across the ever-shining sky. But the imminent death of the Universe will not prevent young Dave from the Turtle tribe from going through the endless jungle in search of the villains who stole the priceless egg of his soul.
