Katie McMullen is a teenage girl, and this is her first book, coauthored along with her grandmother, Carolyn Kivett, and dad, Chris McMullen. Katie had all the great ideas for what teenage girls are into, Carolyn enjoyed working with her granddaughter together on this project, and Chris did the editing and publishing (because what could he possibly know about teenage girls?). Katie also drew the flowers for the front and back cover of the book, and which also decorate the puzzle pages of the softcover edition.
