** spoiler alert ** 
 The Bar Code Tattoo - the first in this series - was one of my favourites growing up. It didn't age as well upon a reread, but when I discovered there was a sequel I decided to see what Weyn had decided to do when it came to continuing on the story. 
 Oh boy. I'm not sure what I was expecting, but it certainly wasn't any of this. 
 Although the writing in the former book wasn't the best, it still had its interesting concept to carry it. The Bar Code Rebellion, however, seems to throw all former crib notes out and continue on a wild tale that tries to include as many tropes as possible - everything from new love interests, to cloning, and eventually even DNA animal/human splicing that isn't ever really explained as to its purpose other than making the protagonist (even more) special. There's also a lot of unimpressive techno-babble in this that doesn't even make sense - 'changing the algorithms' of nanobots due to an autistic girl being able to memorise them in a secret lab where she was brought up (because scientists always repeat their algorithms out loud, right?) - there's so many things wrong with just this deus ex machina example that I don't even know where to begin. It's as if in her haste to include all of the inane plot points earlier that Weyn realised she had to wrap up her book at some point, and hastily forced a happy ending for the flatly written cast. 
 I had zero emotional empathy for anyone in this, and as each page turned I felt further detached from anything going on. I was left very disappointed; it reads like badly written fan-fiction, and it's unfortunate that the original premise was lost so horribly.
