Submit a Query to Kristin Ostby | The Greenhouse Literary Agency

Thank you for thinking of me for your work. To learn more about what I'm seeking to represent, please visit my page on the Greenhouse website.

In short, I am seeking tightly written, tightly plotted, fast-paced commercial middle-grade and young adult fiction—adventure, mystery, and contemporary humor—as well as young adult romance. I am also looking for illustrators who write picture books as well as graphic novelists—particularly those creating works for the younger end of the spectrum (5–7 years).

I do not represent the following: picture book authors (unless you are already a client), poetry collections, short story collections, screenplays, erotica, and work for the Christian/inspirational market.

If you think we'd be a good fit, please fill out the form below. Graphic novelists and picture book illustrators can enter 1 for their word count. (Do not stress about word count.)

Thank you! I look forward to receiving your work.
