literary fictiondiverse voices - Looking for
- Marietta B. Zacker is Co-owner and Literary Agent at Gallt & Zacker Literary Agency. She is always looking for visual and narrative stories that reflect the world as it is rather than narrow bubbles, loves books that make readers feel, and avoids projects that set out mainly to teach a lesson. Across young adult, middle grade, and picture books, she looks for stories where young readers can identify with the actions and reactions of the characters, not the perspective of the author or illustrator, and where diversity is inherent and authentic. She is excited by soulful, insightful, well-crafted literary or commercial projects for any age group from young adult to the youngest readers.
