Isaac's beach read: Gender Queer
Kobabe's 2019 memoir about growing up nonbinary and asexual. It was the most challenged book in American libraries in both 2021 and 2022, per the American Library Association. Isaac reads it in the sun on a public beach, which is more than a lot of school districts would allow.
