RepresentsHorror, fantasy, suspense, thrillers, romantasy, romance
Looking forJenny is currently looking for clients she can co-rep with her colleague James Mustelier. They are seeking all kinds of high concept genre fiction for adults and young adults: horror, fantasy, suspense/thriller, romantasy, and romance. Of particular interest are authors who have successfully been working in the indie space and are now looking to transition into traditional or hybrid publishing, and submissions from BIPOC authors are additionally welcomed. Jenny tends to prefer plot-driven books with strong pacing, novels with an element of magic or fantasy, and stories that are dark and weird in content but traditional in structure and storytelling — she is not the right fit for books with overtly political or extremely complicated plotlines.

Paste the first ten pages of your manuscript in the body of the email — no attachments. For picture books, include the complete text, illustrators should also include a link to your website or two to three PDFs or JPEGs of your work.
