Marcus, the other protagonist, lacked people skills and said some cruel things to Will. I didn't entirely get past a couple of his comments. The reader was shown many reasons to sympathize with him, and I did to some extent, but he didn't have to say things like that. (*spoiler for a comment*) Marcus called Will "retarded." Could not get past that. Just couldn't.
You could understand why Marcus didn't have people skills, and why he had issues. It was a well-written book. So one protagonist, Will, was a quite sympathetic one, and Marcus was less so, to me. I thought it was definitely worth reading.
I ran an errand today and am looking forward to watching tonight's episode of Glee. I think anything after "The First Time" will be anti-climatic. However, it looks like, from previews and spoilers, some interesting things go on.
