When three of the Fantastic Four are lured into the Negative Zone by the evil Blastaar, the Invisible Woman enlists the Silver Surfer to help. But they face an even greater threat: Prodigion, a destroyer of worlds akin to Galactus, the planet devourer to whom the Surfer was once Herald. Can the Surfer atone for his past actions with Galactus? And is Prodigion truly a Negative Zone version of Galactus... or is the truth more deadly than even the world's greatest heroes can imagine?
