Aaron Blabey's Bad Guys series follows a team of villains trying to become heroes, told in a highly illustrated format that reads like a graphic novel but is technically a chapter book. The comedy is physical, the pacing is relentless, and the series has become one of the most reliable recommendations for kids who loved Dog Man and need more.
