"Operation S.I.N." #2 opens with Peggy Carter, Howard Stark and Woodrow McCord on the run, trying to avoid a "THOOM"ing alien craft bearing down on them. The opening scene ends with a whiteout, and from there the real story begins.

Kathryn Immonen has crafted a complete world around the trio and gives each of them a voice, a vice and a fight to struggle through. Carter still fights against sexist treatment from Stark and McCord, despite continuously proving her drive and dedication. This comes wrapped around the external battle the trio is united to stop, adding melodrama on top of pure adventure drama. McCord is a huffing, impatient badger and Stark fancies himself to be God's gift, roles that should surprise no one.

There is no shortage of excitement in "Operation S.I.N." #2, and Immonen gives readers plenty to enjoy, including a meeting with Mikhail Uriokovitch (cue Marvel Zombies fans punching the air in celebration) before the final page of this issue. The small cast welcomes investigation into corners of the Marvel Universe and Immonen follows that invitation nicely. I didn't expect to see this cameo, but now I cannot wait to see who she selects for the remaining issues of "Operation S.I.N."

Rich Ellis handles everything Immonen throws at him and does so while imbuing characters with energy and emotion. His style is rather evocative of Tom Grummett's work, but with less emphasis on perfect hands (seriously, go look at the hands in Grummett's work). He makes the characters his own but does so in a manner that makes them completely and totally identifiable throughout the issue. Jordan Boyd colors the issue with earthy tones and drab fashions, fitting for this gritty espionage adventure. Joe Sabino's letters are on target, masterfully appointed by Sabino and nicely accounted for by Ellis.

The three visual collaborators come together nicely in this comic, giving "Operation S.I.N." #2 an independent look and feel, but Immonen reminds readers that this comic book is not only set in the Marvel Universe but has the potential to be the spine of the Marvel Universe through a generation. While "Operation S.I.N." #2 is largely a transitional issue that shifts characters and establishes settings, there is plenty to enjoy. The best thing about the series is that Immonen and company are writing a smart parallel to the Marvel Cinematic Universe, but it is also one that serves as a spiffy gateway between comics and cinema. Like many of the cinematic outputs, the more you know going into this issue, the more you'll get out of it, but "Operation S.I.N." #2 is as surprisingly inviting to new readers as the first issue was.
