Collapse section Fiction Open Katelyn is looking for voice and quality writing above all else when she falls in love with a new project.On the adult side, she is looking for smart, swoony rom coms and women’s fiction with love that comes in all shapes and sizes; atmospheric ghost stories, thrillers, or mysteries with a strong emotional core and compelling narrators; and sweeping historical and twisty dual-timeline intergenerational sagas.For YA, Katelyn will always have a soft spot for fresh contemporary with a healthy balance of humor and heart. She’s also drawn to magical realism, fantasy, speculative, historical, and light sci-fi, as long as the characters feel relatable and grounded in the teen experience. The same is true for MG, with a special emphasis on capturing all the weird/funny/sad/hard/awkward/beautiful moments that come with growing up. For both YA and MG, she also likes to see a good family and/or friendship story front and center.Katelyn likes picture books that illuminate deeper truths in funny, inspiring, and unconventional ways for young readers, both in fiction and non-fiction.In all areas, Katelyn gravitates toward the unusual and the whimsical, hypothetical questions, and ideas that push boundaries and start interesting conversations. She is especially interested in reading work from diverse and underrepresented voices.Audience:Open to a broad Audience, including: Adults, Children, Middle grades, Young adults.Genres: General Open to all/most Subgenres, including: Historical, Magic Realism, Women's Fiction Fantasy Open to all/most Subgenres Mystery/Crime Open to all/most Subgenres Romance Open to all/most Subgenres Science Fiction Open to all/most Subgenres Suspense/Thriller Open to all/most SubgenresLengths: NovelStyles:Open to all/most Styles, including: Humorous, Mainstream.Topics: Open to all/most Topics.Submissions:Method: Email.

Never pay an agent an up-front fee. That is not how literary agent representation works. Agents earn a commission only after they've landed a publishing deal for you. Also, agents scarcely ever contact writers. If an agent that you haven't queried contacts you about representation, be suspicious. Look up the agent and check if the email address is correct for that agent/agency.
