Welcome to Villain Con! Is Katie the Catsitter actually a villain?! Find out in this bestselling girl (and cat) power graphic novel series that’s perfect for fans of Babysitters Club, Sweet Valley Twins, and anyone who loves cats!

Sometimes the line between villain and hero can be hard to see.

Middle school is a roller coaster and lately Katie doesn't know which way is up or down, who's a hero…and who's a villain. Even the people she cares about most keep surprising her. Are Katie's best friends leaving her behind?! Katie just wants things to stay the same—but is she holding her friends…and herself back? Maybe it's time for a change. Afterall, Madeline is running for mayor to try to change things in the city. Maybe Katie's changing too. Maybe some of the things she thought she knew about villains—and about heroes—were wrong. Is Katie ready to move forward…even if it means moving away from her friends?

Get ready for more drama and disguises, more friendship and fun (and cats, definitely more cats!) in Katie the Catsitter: Villain Con!
