Stan Lee's Riftworld

TWO HEROES-THREE WORLDS IN CHAOS!
The Rift, an inter-dimensional wormhole connecting many worlds, can be traversed only through the power of the mind. And the only person on Earth who can manipulate it is John Cameron, new artist at the Fantasy Factory, a comic-book company headed by legendary mogul Harry Sturdley.
When Cameron transports to Earth a group of twenty-foot-tall giants from another world, Sturdley gets them under contract to star in a series of comics. But the giants have their own malevolent agenda, and when they attempt to kill John Cameron, all hell breaks loose. Wounded, John teleports himself and Sturdley to a planet where everyone seems to be superpowered-including the criminals whose release is precipitated by Cameron's arrival!
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!
