Not really sure where to begin with poison study. Here you have a story about a country ran by the military, a girl in prison for murdering a sick slave owner just to gain her "freedom by becoming a food taster. The concept was original, the world building was OK, the plot wasn't too predictable and the characters were lovable. Yet, it was soo slow! I'm not saying it lacked action. There was just so much detail and so many small clues without much of a hint to what the big picture was. I like a good puzzle but the book seriously didn't grab my attention until about page 290 of 361. I could just be a super picky reader that's impossible to impress, that's possible. But let me put it this way. I feel a hell of a lot more positive knowing that I borrowed it from the library.
