3.5 rounded up. The main character, Gwen, is really unlikeable and makes so many stupid decisions. Her tendency to cover discomfort with jokes was more annoying than cute. The other characters all felt incomplete and I couldn't quite figure out their point.

The plot was clever and I didn't see the twist at the end coming, so that was good! And it was pretty easy to read and thankfully there weren't too many characters to keep track of.
