Jonathan Rosen

The Seymour Agency

My Manuscript Wish List®

I’m an agent at The Seymour Agency, and looking to represent a wide variety of genres.

In Kidlit, I want YA, Graphic Novels, non-fiction, and will consider PBs and Chapter Books. (Not looking for MG at this time)

In adult, Mysteries (All types), Thrillers, RomComs, Historical Fiction, Non-Fiction

Being of Jewish-Mexican descent, I will always have an eye out for diverse voices, and in particular ones that reflect my background.

Humor is good in any genre, and do love quirky. My tastes run to extremes. I can like dark in one book, while also wanting light and hopeful in another. I really do like a wide variety.


Fun facts about me:

I have lived in several different countries, and moved around a lot as a kid. I co-host a weekly YouTube show where we interview many different celebrities.
