Melanie Castillo is a literary agent at Root Literary. She represents middle grade, YA, and adult fiction along with select nonfiction titles. What she loves most about the job is the balance of creativity and an entrepreneurial spirit. After graduating with a masters in writing and book publishing from Portland State University, she worked as an editorial project manager at Quarto and then as a freelance editor for several years before joining the agency in 2018. Melanie was born and raised in Southern California in a multicultural, blended family, so she has a soft spot for books that shine a spotlight on the nuances of relationships and identity. She currently lives in Long Beach and can be found on Twitter at @wellmelsbells.


I'm actively looking for fiction and narrative nonfiction. I'm especially excited to find high-concept commercial and literary leaning general fiction, young adult novels with a strong voice and propulsive pacing, and heartfelt and humorous middle grade novels across genres.
