I just finished 'The Perks of Being a Wallflower,' it has a lot of sensitive characters, albeit I assume since it's in journal form and centers around a kid developing social skills and observing peoples actions and emotions it's supposed to have that sort of tone.
Right now I'm finishing The Foundation trilogy. Really cool book centering around mob pyschology, affluence, playing politics, and all of its consequences, all in the setting of a science fiction.. At least that's what I focused on.
After that, I'm going to read Rifles for Watie, it's about a young Union soldier fighting Cherokee confederate rebels. Another book in my sights is Shutter Island which is a horror about an insane asylum.
