Marvel's Iron Man 3 Prelude by Will Corona Pilgrim, Ramon Rasonos, Christos Gage

Iron Man 3 Prelude, aka What Jim Rhodes Was Doing During The Avengers.

There is also a mostly pointless comics retelling of IM2; only "mostly" because it is nice to see Tony customizing War Machine for Rhodey and Rhodey's first flight, which are major plot holes in the movie. There is also a lot less Vanko and Hammer, but counterbalancing it is a lot less RDJ.

Also includes the first issue of Iron Man: Extremis, which I assume is massively confusing for people not already familiar with the comicsverse. Not that you can't read Extremis cold, but one chapter included in a book focused on the Cinematic Universe, without any prior indication that this is from a different continuity, is not the best way to go about it.
