UnWholly by Neal Shusterman takes place a little after the end of Unwind. We are immediately introduced to a new character, Starkey, who is undoubtedly going to be the villain of the piece, who vies with Conner (our protagonist from the first book) for leadership of the Unwinds. We are then in short order introduced to new characters in the next few chapters all who have eerie resemblance to the ones we all know. Miracolina is the poster child for a tithe, a person who is raised to be unwound. She is our new Lev. And so on. The story revolves around these new characters, and the struggle of Connor, Risa, and Lev to keep their ragtag band of teenagers safe from being unwound. It's a thankless job. The most unique addition to this group is Cam, a composite created from many Unwinds, taking the best from them and putting them all together in one being a modern day Frankenstein. I believe that this introduction saves the book.
