This is a full review of Rebel Rising, and contains spoilers.
I was so, so excited to start this book. Ever since seeing & falling in love with Rogue One, I was always curious to know more about Jyn and Saw's relationship, and the long gap of time stretched between Lyra's death and Jyn's time at Wobani. However, I found this book to be colossally disappointing and underwhelming in the scheme of Jyn's canon life, for a number of reasons.
This book betrayed me into thinking it was interesting by starting with a well-built, deeply interestingly portrayed relationship between Jyn and Saw. Sometimes it felt a bit one-sided if only because of the narrator's everpresent stance behind Jyn, but generally, their relationship was endearing and well-crafted as we learned of all the things he taught Jyn in her youth. However, the day Saw abandoned her felt like a complete, rather out of character curveball, and the book went downhill from there. We still have no idea what Saw's motivations for doing such a thing were, and, as an audience, are still blind to his thoughts, feelings, and activities between abandoning Jyn and when he meets her again in Rogue One. I think the book could have really benefitted from some dual perspective, but that would also require Jyn sharing a spotlight with Saw in terms of main perspective, yet still... I wouldn't complain.
I found Jyn's whopping two years spent with Akshaya and Hadder to be extremely poorly written, tedious, and wrought with missed opportunities. Jyn's place in the Punta household was, essentially, as a replacement for Akshaya's dead daughter/Hadder's dead sister -- yet the book forced an embarrassingly-YA-cliche romance between Hadder and Jyn anyways. Their love life was utterly baseless, and, just like Saw's abandonment, came out of the clear blue sky. I found it to be horrifyingly out of character for Jyn to feel those types of feelings in return for Hadder, if only because in the scheme of the book she had seemed so utterly uncomfortable and standoffish in response to any kind of physical affection of praise. Not to mention, it seems like Jyn had never had any friends her age, but had grown up with Galen, Lyra, and Saw's group of adult partisans. I'm not sure where her finesse with romance (and, as implied, sex) came from, but I found it to be cringeworthy and out of place. If Hadder had been set up as a brother figure rather than a boyfriend, it would have made his eventual (and, might I add, extremely vague and underwhelming) death much more impactful on Jyn, who has deep ties to familial relationships. But that's just my two cents on the matter.
I didn't hate Jyn's time spent on the city planets. I liked the way the setting was described, and I liked feeling secondhand stress about how this young girl was all alone in this huge planet with just the shirt on her back, her weapons, and her limited amount of credits. I thought it was set up well.
I also minorly enjoyed the Imperial officer who had a gambling problem. I thought it was interesting to view an Imperial who wasn't absolutely-downright-evil, like most of the other Imperial offiers we're forced to see in the scheme of the Star Wars universe.
However, I thought a lot of the events that came after Hadder and Akshaya all felt very... forced and convenient. I didn't feel as though any of the events had a natural flow, if that makes sense. I always felt as though Jyn was more stepping willingly into the next plot point that would advance her story rather than her walking through the journey realistically, as poorly phrased as that criticism is.
Oh, need money? Here's an Imperial officer who will pay you handsomely to help her. In trouble with gangsters? How lucky it is that you know how to forge documents for them. On a ship full of slavers? Good thing you know how to fight and knock all of them out. None of these events were all that enjoyable to read about, and in fact, kind of planted a distaste for Jyn and her mindset that I didn't previously have watching Rogue One.
Her actions and perspective are understandable, but the way the book constantly reminded me of her ill-founded hatred for the Rebellion and odd leaning-towards the Empire and general apathy towards injustice irritated me significantly. It left me wishing I hadn't read the book, if only to preserve my favor for Jyn.
The book did have some strong moments -- I thought her time on Wobani was much more well-written than the rest of the book, honestly -- but generally, it isn't worth it for the practically 250-page drag that this book has.
I'd probably give it 1.5/5 stars without much wiggle room, and wouldn't recommend it to people interested in Jyn Erso's backstory. Instead, I'd just say, "Imagine your own backstory for her, however you like. It'd probably be more interesting than Rebel Rising."
