I'll start out by saying that I can't really control my thoughts, I'm easily distracted and confused, and I'm still going through a lot of major personal stuff, but this book was HARD AS HELL to follow. Long scenes were summed up in a couple of sentences, the main character talked to himself constantly (although this might have been a symptom of his Tourette's), and characters came and went.
All in all, not a very enjoyable read, especially since the story took some bizarre turns near the end, but a promising premise and a decent book for teens who also have Tourette's (if not solely for the fact that you'd be hard pressed to find another YA book with a main character who has the affliction, and that he learned to live with himself and not feel like he was damaged).
