This is really good. 
 And I don't just mean good as in "This is pretty good for a tie-in comic book." I mean that this is seriously good as in, "We should use plastic surgery to alter Jason Aaron's appearance so that he is identical to George Lucas. Then we'll invent time travel and send Aaron back to 1999 where he will kidnap and replace Lucas. He will then write better prequels and save us all from much misery and suffering." 
 That's how good it is. 
 Set shortly after A New Hope, the good guys are trying to infiltrate and destroy an Imperial weapons manufacturing factory only to have their plans complicated when Darth Vader shows up, and during the ensuing battle he gets seriously interested in that untrained kid waving the lightsaber around. Unaware that Vader is on his trail, Luke is getting frustrated that he has no one to train him to be a Jedi while Leia urges the leaders of the Rebellion to keep pushing their temporary advantage against the Empire, and she's continually frustrated by that scoundrel Han Solo who keeps hanging around. 
 There's a lot of smart choices here that build on the events of the first movie. It all flows together in a very organic way, and all of this stuff makes for a compelling story that starts to bridge the gap between A New Hope and The Empire Strikes Back. In addition to that the characters are very well done so that Han Solo in this comic really feels like Han Solo, and it's not much of a stretch of the imagination to see a young Harrison Ford saying these lines. The art is also very well done with great details that all feel very Star Wars while still having a great sense of pacing for the action. 
 I did have a small issue with the way that Boba Fett is shoehorned in here. It makes sense that Vader might hire a bounty hunter to backtrack Obi Wan Kenobi and figure out who that kid with him was, but bringing Fett in means that things have to get cute when he confronts Luke because the subsequent movies don't indicate that they had any previous meetings. That part does feel like a bit of forced fan service. 
 Still, this was incredibly fun. It feels like you're reading the script and storyboards to a long lost Star Wars movie.
