Fanny Fitzpatrick has the coolest best friend ever. Athena is smart, and pretty, and brave, and kind. Fanny loves her friend, but sometimes, she feels a little jealous of how perfect Athena is.

But even "perfect" girls make mistakes, and Athena makes a big one when she accidentally turns the school bully into a cockroach. He was picking on their friend Gemma and Athena lost her temper and her magic powers just slipped out right in front of Fanny.
Now Fanny knows that Athena isn't an ordinary girl – she's the reincarnation of a Greek goddess, powers and all – and now she needs Fanny and Gemma's help to hunt down the bully-turned-cockroach and turn him back into a human boy.
Fanny doesn't want to spend all her time looking for a cockroach. She's got the Junior Miss Super Pretty Pageant to prepare for, if she can get over her stage fright. Besides, Athena's Dad, Zeus, has forbidden the girls from meddling with any more cockroaches or magic, and Zeus is a god you don't want to mess with.

Fanny has to make a choice. Should she pursue her pageant dreams, or risk Zeus' wrath to find the cockroach-boy? What's the right thing to do? And how do you hunt down a cockroach anyway?
