Nimona really shows the thin line between being a hero and being a villain. Throughout the story, the characters changed from noble to not-so-noble motives or vice versa. It was witty and funny. The dialogue was humorous and sometimes random, but it worked with the plot. I love a good villain, and this book was jam-packed with all sorts of villains, the good ones, the bad ones, the misunderstood ones, cool ones, mean ones and everything else in between. The idea was original and it was executed perfectly.
