The nation’s largest publisher and several bestselling authors, including novelists John Green and Jodi Picoult, are part of a lawsuit filed Thursday challenging Iowa’s new law that bans public school libraries and classrooms from having practically any book that depicts sexual activity.

The lawsuit is the second in the past week to challenge the law, which bans books with sexual content all the way through 12th grade. An exception is allowed for religious texts.

Penguin Random House and four authors joined several teachers, a student and the Iowa State Education Association — the state’s teachers union representing 50,000 current and former public school educators — in filing the federal lawsuit.
