Everyone's favorite Mackerel Middle-Schooler, Jamie Kelly, is back with another hilarious, candid (and sometimes not-so-nice) diary!

There's a new girl in at Mackerel Middle School.

Colette is friendly, fabulous, smart, totally talented, and an all-around amazing individual. She is more brilliantly diabolical than Isabella, as blindly loyal as Stinker, and even harder-to-resist than Angeline. It's enough to make Jamie throw up a little. And Jamie just can't help but wonder: Is it humanly possible for a girl to be more perfectly perfect than the most perfect girl in the world?
