About Katelyn

Katelyn lives, works, and writes in Brooklyn, NY. Literary agent by day and writer by night, Katelyn is the author of four YA novels, including her latest release, The People We Choose.

Katelyn Detweiler was born and raised in a small town in eastern Pennsylvania, living in a centuries-old farmhouse surrounded by fields and woods. She spent the vast majority of childhood with her nose in a book or creating make-believe worlds with friends, daydreaming about how she could turn those interests into an actual paying career. After graduating from Penn State University with a B.A. in English Literature, emphasis in Creative Writing and Women’s Studies, she packed her bags and made the move to New York City, determined to break into the world of publishing. She worked for two years in the marketing department of Macmillan Children’s Group before moving in 2010 to the agency side of the business at Jill Grinberg Literary, where she is currently a literary agent representing books for all ages and across all genres.

Katelyn lives in a cozy Brooklyn apartment with her husband Danny, her son Alfie and her daughter Penelope, surrounded by stacks of books and records and diapers. When she’s not reading or writing or taking care of a tiny human, Katelyn enjoys yoga, fancy beverages, and road trips. She frequently treks back to her hometown in Pennsylvania, a lovely green escape from life in the city, and her favorite place to write.
