New York Times bestselling author Michael Buckley's The Villain Virus is the fourth book in the hilarious NERDS series.

Supervillain (and former NERD) Heathcliff Hodges transformed himself into an all-powerful giant head, and now he's unconscious in the HQ basement. Though he's knocked out, the villain population skyrockets in just a few short days. Normal people get a cold and then suddenly develop insane alter egos and come up with elaborate plans to take over the world.

Even the NERDS are vulnerable to the spread of villainy--all except hyperactive Julio "Flinch" Escala. But he's never led the team before. Can he focus on more than his next candy bar . . . and save the world?
