Aya's story starts out slow. Her brother is famous, everyone watches his feed and Aya's still trying to make her name, find her story.
It isn't until she gets in with the Sly girls that things get a little interesting. Sly girls do crazy tricks just for the sake of doing them, not to be famous. About halfway through the novel, I found myself seriously missing Tally, because as far as Aya goes, she's just not my favorite character. I disliked how she taped the Sly girls, and still got to use the footage. How on earth could they have been okay with that? The whole point was that no one would know. The ending gets dramatically messy, Tally shows up briefly, and I can't even like her. She just seems so cold and heartless, it's odd.
Extras just made me miss the good old days of Uglies, Pretties, and Specials. It wasn't a bad novel, but it wasn't amazing. It was just there.
