A note for parents

On a Sunbeam is a thoughtful, character-driven science fiction graphic novel centered on LGBTQ+ themes, particularly a sapphic romance. The story emphasizes emotional growth, found family, and self-acceptance while maintaining a generally hopeful tone despite some darker moments. The content is generally age-appropriate for mature teens, though some mild violence, occasional language, and romantic/emotional intensity warrant a teen reading level.
