Otherwise

Summary: "In a near-future United States, unisex gender presentation becomes mandated by law. In short free-verse lines with occasional rhyme, a narrator of unspecified gender explains that Pennsylvania has just become the final U.S. state to pass this legislation, and "in 30 days / this will be our law: / No Gender Specified." Under the new law, everyone must shave their heads, wear body-shaping suits, take voice-altering medication and avoid asking names of other people. When the narrator, who takes the name Spark, meets Whistler at a campground, the teens are instantly drawn to each other." - partial Kirkus review.
"It's the law. There will be no more genders. Everyone must appear gender neutral. no more boys. No more girls. Just...otherwise. 'Spark' dreads the future. The she meets 'Whistler'. But who is Whistler? And what is Whistler? Boy? Or girl?" - back cover.
