Stan Lee's Riftworld

The superheroes are here-with murder on their minds.
When twenty-foot-tall giants materialized in New York City, it seemed that real superheroes had arrived to help the world.
And Harry Sturdley, head of America's biggest comics publishers, wasn't slow to sign them up-and design their costumes.
But the giants have their own agenda. And their first objective is to eliminate John Cameron, comics illustrator and Sturdley employee, who possesses the unique gift of manipulating the Rift, the gateway through which the giants have travelled.
Cameron, with Sturdley and his assistant Peg Faber, escape through the Rift, but only as far as the giants' home world, where human life is cheap and warfare is constant. But the planet conceals a secret which could be humanity's only hope.

Stan Lee, Marvel Comics' legendary originator of Spider-man, The Fantastic Four, The Hulk, and the Silver Surfer, with New York Times bestselling author, Bill McCay, forges an epic new series out of the world of comics and into another-Riftworld!
