Well, as a student (i study some languages and try to improve eng) I was really afraid about reading books - what if I just waste my time and money without results??? But.. You know, I've finished this one and another (medicine topic), so.. I can say it is really cool!
I felt soulfully well when I read them) I suppose, it's more important than a large texts that you can't understand or feel annoyed about process.
So, probably, I prefer stories about ill people with disorder personality, feelings, mind.. and about surgeries))
