Will the perfect senior prank turn out to be Emlyn’s last?

Emlyn is a good girl. She is every parent and teacher’s dream. But Emlyn has a secret. She has an entire library in her head filled with terrifically terrible plots and schemes: jewel heists, corporate espionage, and other mischief. She successfully hides her desire to be bad from the world. That is, until Jack, Mavis, Lovell, and Donovan approach her with their idea for a senior class prank: to steal the famous mummy, Amaral-Re, from their local museum. Now Emlyn’s “mental library of Bad” will come in handy.
