Johanna V. Castillo

Senior Agent at Writers House

My Manuscript Wish List

Johanna is actively seeking fiction: adult historical, book club, or upmarket fiction, but especially romantic comedies. If it's romance, with none of the comedy, she wants high stakes and heart wrenching storylines. Think Colleen Hoover's It Ends With Us, Ian McEwan's Atonement, lovers in dire circumstances or lovers who are the dire circumstance.

Johanna edited most of Collen Hoover's titles during her time as an editor at Simon & Schuster. She has acquired and edited 44 New York Times best-sellers.

In YA and MG, Johanna is looking for compelling BIPOC protagonists.

Unreliable narrators, generational narratives, diverse retellings of classics, unconventional family dynamics, bickering lovers, and enemies-to-lovers are some of her favorite tropes.

She’s open to representing fantasy and thrillers, but primarily if they have a strong commercial appeal or literary slant.  She edited The Map of Time by Feliz J. Palma and The Elizas by Sarah ShepardShe’s always looking for stellar and engaging writing, and stories that mean something.

Her fiction clients include authors such as Isabel Allende, Reyna Grande, Naina Kumar, Christine Kandic-Torres, Armando Lucas Correa and Agustina Bazterrica.

While known for spearheading memoirs and nonfiction, Johanna’s non-fiction list is highly selective at this time.

Johanna is NOT looking for: poetry, hard science fiction, epic or high fantasy, kidnapping storylines, gore, strong horror.
