Marvel has made available the entire Jonathan Hickman Fantastic Four run, on their App, for only 99 cents each.
That's issues #570-588, for a total of 19 issues.
Issue #570 starts off with the cosmic-heavy "Solve Everything" arc that sees the Council of alternate universe Reed Richards introduced. They are sporting Infinity Gauntlets, the Starblast and more - as they take on the Celestials!
Of course the run concludes with #588 -- the post-death issue of Johnny Storm!
I'm not sure how long this lasts, but be sure to get it while it's -- wait for it -- hot!
