The Metatherions and their powers to warp space and time threaten all life as we know it! And the only way for the Cosmic Patrol to fight them is by braving a trip through the Gern Gravastar, an extradimensional portal leading to the Metatherions native plane. Only, the Gravastar is steadily growing in size, and nothing can slow it down. Unless it can be stopped, the Gravastar will eclipse whole systems, the entire galaxy - perhaps even the universe, itself!
