The Hulk can find enemies anywhere, even on a sub-molecular level--but love long eluded him until his atom-shattering romance with Jarella! The tiniest of worlds offered him all that he ever desired--but when the Hulk fights his way through obstacles on both Earth and K'ai, what will be left waiting for him? Guest-starring Doc Sampson and Captain Marvel, with appearances by Spider-Man, the Thing and more! 'Hail Hulk!'"
