When I first started this book I was a little unsure of it. The main character, Samantha was just so unlikable at the beginning! Eventually though it became clear that you weren't really supposed to like her. She was rude and insulting, and pretty much everyone realized this but her. However, one day she accepts a bet from her coworker to go two weeks without insulting someone. Pretty quickly she comes to realize how hard this task if for her, and predictably, we start to see a change in Samantha.
As is expected, Janette Rallison's book are not deep or surprising, but they are always funny and have a heart. And while on the surface All's Fair in Love, War, and High School seems like simply a fun, fluffy read - it really does have so good messages about kindness and how the way we treat others does define the person that we are. A good message for a book aimed at teenagers.
