It's always the case - The books you go into with the least amount of expectations are almost always the ones to blow you away.
Neal Shusterman has an incredible Voice, and knows how to tell a story with it. Unwind
is an extremely good piece of writing with some solid characters that stay with you for a long time. The book is disquietingly realistic and scary as hell, and whatever flaws in the book, are forgivably small.
BUT JESUS THE SCENE WHERE ROLAND HAS TO LIE THERE AND WATCH THEM CUT HIS BODY INTO PIECES MY GOD WHAT WAS UP WITH THAT SHIT IT WAS GUT-WRENCHING IT FELT LIKE SOMEONE PUNCHED THE AIR OUT OF ME I ALMOST THREW UP MY LUNCH THE FUTURE IS A TERRIBLE TIME TO LIVE INSPOILER!!
You will cry.
