Marvel Ultimate Graphic Novel Collection Issue 83 : Fantastic Four Voyagers

Marvel's First Family are heading out into the great unknown on the adventure of a lifetime! With Franklin and Valeria in tow, Reed, Sue, Johnny and Ben take a journey across the universe — and even to the past and future — on the ultimate educational road trip. But little does his family suspect that Reed Richards has an ulterior motive for their sabbatical through space and time — one that could mean the end of the Fantastic Four.

Collecting Fantastic Four (Vol. 4) #1–8.
