A book for a young adult audience that the American Library Association described as “the most banned book in the country,” is now under scrutiny for rejection from bookshelves at private stores.

A Republican Virginia state delegate has filed a lawsuit against the author and publisher of “Gender Queer,” a book about the nonbinary and asexual experience, demanding the Barnes & Noble require parental consent before selling the book to minors. State delegate Tim Anderson and his client Tommy Altman, a state congressional candidate, said on Wednesday that “the Virginia Beach Circuit Court has found probable cause that the books ‘Gender Queer’ and ‘A Court of Mist and Fury’ are obscene to unrestricted viewing by minors,” according to a Fox affiliate.
