A while ago, I read "Full Tilt" by Neal Shusterman. Less long ago, I read his Skinjacker's Trilogy ("Everlost", "Everwild", and "Everfound"). In all of those books, Mr. Shusterman created a chilling and suspenseful tale that tended to highlight choices, the lack thereof, and terrifying worlds that you could never imagine being reality. Unwind is those things as more.
Horrifying. That is a predominant word I would use to describe Unwind. The (what one would consider dystopian) world that Unwind is that way. There are situations that the characters get into that are just gut-wrenching. It's bad. There's also a scene involving a character that you thought you hated, and up until that moment, you did-- but it's just the most emotional thing and it's scary, and the confused way it's written just amplifies that. Also, the story is written mostly from Connor, Lev, Risa, and Ci-Fy (love that name, by the way) point of view; but there are lots of others mixed in sometimes for a few parts and sometimes for only one. Each of them seem to see each other, their situation, and the whole world very differently and that was impressive and very useful to widen your opinion of each other characters.
Apparently, there's a sequel to Unwind coming out called Unwholly (about 5 years later! It's scheduled for September 2012) and I look forward to more of this chilling story. Also, thank you KT for
