I like most books, particularly children's and YA. The fact that I am 21 does not and will never hinder this, and it shouldn't. A good book is a good book is a good book.
Anyway.
I'll read anything I can get my hands on if the mood suits me.
Tough reading (it was required for a health class) mainly because MAN, Gawande does NOT skimp on the details of surgery and some of the descriptions were gruesome, but gripping nonetheless.
