In what may be my most controversial take in a Goodreads review since I rated Anna Karenina 2.5 stars, I actually mostly enjoyed Aftermath. For those of you who don't know, Aftermath is widely considered to be one of the worst, if not the single worst Star Wars book ever written by fans of the franchise. On this point, I wholeheartedly disagree. Honestly, there are worse Star Wars books than this even in the modern Disney era. Like Last Shot, a book about Han Solo and Lando Calrissian that was so awful and un-Star-Wars-like that I couldn't stand it anymore and DNF'd it. If I could summarize my thoughts on this book in a single sentence, it would be this:
Chuck Wendig can write, and Chuck Wendig really CANNOT write.
What do I mean by this? ...
Story
The story in this book is where Wendig succeeds. To me, this does feel like a Star Wars story. It blends frenetic action sequences with TIE fighters, star destroyers, and a rebel fleet with political backstory. In this way, it felt a lot like Star Wars Episode I: The Phantom Menace to me, which similarly blended action and lightsaber battles against a backdrop of an Imperial blockade (which this book also has). The book also nailed the upbeat tone that Star Wars stories tend to have, and the tendency for something to always be happening and for things never to be boring. In this aspect, the book really shines, and it's the reason I didn't DNF it and generally enjoyed picking it up every time I wanted to read.
Unfortunately, however, this is really where the positives end for Aftermath...
Writing
The writing in this book is objectively awful, and is among the worst I've ever read in my life. Wendig writes in a stunted, edgy way where he omits the first word or two of many of his sentences in an attempt to make the writing more slang-ey and hard-edged, but it just comes across as juvenile. Your high school English teacher would absolutely flog you over the head for writing like this in even a short story for English class, yet somehow this writing made it into the flagship novel of the Disney canon of Star Wars, the book meant to begin to bridge the gap between The Return of the Jedi and the (at the time) upcoming new film, The Force Awakens. It astonishes me that this happened; it's almost like no one edited this book at all, because the writing is truly awful.
And Wendig constantly uses these annoying, goofy, stupid "like" and "as" analogies that are completely ineffectual. He does them at least once per page for the entire 410 pages of this book's length, and sometimes even does them in back-to-back paragraphs. He'll say something stupid like:
"He stepped out into the rain, and soon he was as wet as a Bantha caught in a monsoon."
And more than once he compares something to a "lizard monkey". But the problem with the hundreds of lame, cringe-worthy analogies Wendig makes is that he never explains what any of the things he's comparing something to actually are. Like, a lizard monkey? What does that look like? Which animal's head does it have? Is its body covered in fur, like a monkey? Or does it have smooth, reptilian skin? Because Wendig never explains any of these things, the analogies have no meaning, and when combined with their corny nature, they just end up being stupid. They should have been cut from the novel completely, because they were just empty words and they made the book insufferable to read through at times.
There are also things like swearing (multiple times) and references to sex that never occur in Star Wars and that felt completely out of place. I think with these things, combined with his juvenile/stunted writing style, Wendig was trying to bring a new edginess to the Star Wars universe, but to me they just felt incongruent with what Star Wars has always been, and they made the story slightly worse (in my opinion).
There were also numerous character death fake-outs in this book that I rolled my eyes at as they kept occurring, because you knew Wendig would never kill those characters. So when they magically appeared each time ("they're not dead after all!"), it had no effect and was just cringe-worthy because of how predictable it was. These repetitive character death fake-outs became more and more annoying as they continued to occur throughout the book.
Characters
In addition to the writing, the characters in this book are a serious problem for many reasons. Chief among them: there are way, way too many. There must be at least fifty characters in this book, and after a while it felt like Wendig was just throwing them in to try to break some kind of record for most characters ever in a Star Wars book, because the vast majority of characters in this book are just name dropped, and maybe featured in a single scene on a single page, and then they are never mentioned again for the rest of the book. They were completely ephemeral and unnecessary.
The other main problem is that, of the four or five characters you do follow for any significant amount of time in this book, they are all boring stereotypes of Star Wars characters that bring nothing new to the series: there's the hard-nosed bounty hunter, the boy character with mommy and daddy issues (à la Kylo Ren and Luke Skywalker), the "droid you're supposed to love" (à la C-3PO, R2-D2, and BB-8), the conflicted Imperial who wants to turn to the light side (à la Finn, Darth Vader, Kylo Ren), and the ruthless Imperial evildoer. It's all very formulaic. And on top of that, most of these characters either aren't well-developed or are just terrible.
The drunk Imperial who wants to turn to the light was an arrogant, self-absorbed prick, the droid was one of the battle droids from the Prequel Trilogy who mostly just said stupid things like "Roger-roger!" constantly (thus making himself look more like a cringe-worthy parody of a Star Wars droid than anything else), and the mother character in the book acts completely against everything she says and is extremely self-contradicting (she talks about how her son is the most important thing in her life constantly, but throughout the book she almost gets killed numerous times because she wanted to be a renegade and recklessly put herself in danger, almost orphaning her son several times).
Verdict
For me, Aftermath was largely an enjoyable reading experience because it truly feels like a Star Wars story that could be adapted directly onto the big screen, and its upbeat atmosphere, constant excitement, and clever blend of action and politics are aspects of the Star Wars formula I've seen other authors in the series fail at completely. But the book is also deeply flawed, featuring probably the worst prose I've ever read, far too many and paper thin characters, insufferable/goofy/completely ineffectual/way too many dumb analogies, and aspects of life that just don't belong in Star Wars (swearing, references to sex). If you're looking for a book that feels like Star Wars, or if you're a series completionist, this may be worth checking out, but know that it's deeply flawed and considered one of the worst Star Wars books ever written by much of the Star Wars fandom.
