From back of book: As Sputnik silently circles in the skies above the fabled cities of the United States--Metropolis, Washington, DC, Chicago, Los Angeles, Gotham City--danger lurks in Earth's darkest corners. Evil genius Lex Luthor, Superman's archenemy, is leveraging international tensions to build a military-industrial empire, competing against his business rival Wayne Industries, which is run by Gotham City's enigmatic millionaire, Bruce Wayne. Meanwhile, the shadowy vigilante known as the Batman haunts Gotham's streets...and the police are just as afraid of this Dark Knight as the criminals.

In Metropolis, Dily Planet reporters Clark Kent and Jimmy Olsen are investigating the rumored crash of a flying saucer. Clark is desperate to know if there may be other lost interplanetary visitors on Earth secretly living among us--visitors like himself. Their colleague Lois Lane is on an assignment of her own, pursuing a dangerous exposé of LuthorCorp secrets.

As America and the USSR race to build bigger nuclear missiles aimed at each other's great cities, two extraordinary heroes--polar opposites in their attitudes and actions--unite to fight evil and injustice, and add an exciting and unforgettable new chapter to their storied legends.
