The Bad Girls series follows Mikey Elsinger and Margalo Epps from the moment they meet in fifth grade through their high school years. Voigt writes the friendship with genuine humor — the two girls are different in nearly every way, which generates most of the comedy, but their mutual respect and loyalty hold the series together across seven books and several years of fictional time.
The series spans 1996 to 2006, with The Seductress (2016) arriving a decade after the main run, revisiting the characters as adults. Voigt keeps the tone lighter here than in the Tillerman books — the Bad Girls series is genuinely funny, and the friendship at its center is one of the more honest portrayals of female friendship in middle grade fiction from that era.
