Summary 
From the book jacket
On the planet Xhaldia, ordinary men and women are mutating into bizarre creatures with extraordinary powers. But is this a momentous evolutionary leap or an unparalleled catastrophe? The very fabric of Xhaldian society is threatened as fear and prejudice divide the transformed from their own kin.

Dispatched to cope with the growing crisis, Captain Picard and the crew of the starship Enterprise receive some unexpected visitors from another reality – in the form of the group of mutant heroes known as the uncanny . , leader of the X-Men, offers their help in resolving a situation that is agonizingly similar to the human/mutant conflicts of their own time and space.

But when hostile aliens appear in orbit around Xhaldia to try and abduct the transformed for use as a superpowered force in an attack on the Federation, even the combined forces of the crew of Starfleet and the X-Men may be unable to prevent an inferno of death and destruction.

Starfleet's finest crew and Earth's greatest mutant heroes will need all their powers and abilities to save the Xhaldian people and stop a deadly threat to the Federation.

Background information 
 The novel came out of Paramount's collaboration with Marvel, Paramount Comics. After producing a crossover between the X-Men and the Original Series crew, discussions with Pocket editor John Ordover led to the suggestion of expanding the planned Next Generation follow-up into a comic and novel combination. As a result, the novel is set in the same continuity as the comic "Star Trek - X-Men II: Second Contact", and references events from that story. ()
 The novel is set sometime after  ("Second Contact" occurs immediately after that film)  and the  episode  (as Worf and Jadzia Dax are recently married).
 A mutual resemblance between Professor Xavier and Jean-Luc Picard is mentioned when Crusher creates a holographic duplicate of Xavier to help investigate the problem on Xhaldia. Although the book was written and published long before the first X-Men movie was cast, this proved to be canny foreshadowing, as Patrick Stewart would go on to play Xavier in the X-Men movies.
 At one point, Worf, Banshee, and Archangel beam aboard an enemy ship, accompanied by three Enterprise guards named Ditko, Kirby, and Lee. These are references to Marvel writers/illustrators , , and Stan Lee.
