The NERDS series combines the excitement of international espionage with the awkwardness of elementary school as it follows the adventures of a group of unpopular fifth graders who run a spy network from inside their school. With the help of cutting-edge science, they transform their nerdy qualities into incredible abilities, and the results are awesome, inspiring—and hilarious.

A virus has infected Arlington, Virginia, home of NERDS headquarters, and it’s much worse than your run-of-the-mill flu. Instead of coughing and sneezing, the victims of this voracious virus are transformed into superintelligent criminal masterminds. Soon nearly everyone—including some of the NERDS team—is plotting to take over the world. And who’s to blame for this nasty infection? None other than former NERDS teammate Heathcliff Hodges. With more people breaking out into evil cackles every day, it’s up to Flinch, the hyperactive superspy with a sweet tooth, to stop the virus. He needs to destroy the virus at its source, and to do that he’s going to have to get inside Heathcliff’s head—literally. Flinch will have to miniaturize himself and take a fantastic voyage through the supervillain’s body to fight white blood cells, stomach acid, and a nest of nasty nanobytes in the hope that he can save the world from . . . the Villain Virus.

    The fourth book in this series has an awesome cliffhanger! It is a must read! Agent "Flinch" is observing a virus that seems to turn everyone into villains (hence the title of the book). When he too gets the virus, he discovers that he beat it and he is now immune to it. Unfortunately, the same cannot be said about his teammates. When his teammates turn against him (and themselves), Flinch has to go in the body of Heathcliff's (their former teammate) body to turn off the source of the virus. But there might be another traitor in the midst...

        This book was my favorite in the entire series. Maybe because it was in the POV of my favorite character. The ending was unexpected. Overall it was a very good book

          AWESOME! This is the kind of problem I want to read in books. Everyone going against you and you almost can't stop them.
