Jennifer Jackson has been an agent with the Donald Maass Literary Agency since 1993, and is a member of the Association of Authors' Representatives. She believes in a hands-on approach with a focus on career planning and editorial support.

Jackson grew up reading science fiction and fantasy, and initially concentrated her endeavors in that field. She continued by pioneering the expansion of the agency into the areas of romance and women's fiction, and is also developing her list in the mystery and suspense genres, as well as YA. Her current roster includes New York Times best-selling fantasy writer Jim Butcher, science fiction author Elizabeth Bear, USA Today best-selling author Anne Bishop, Derringer-Award nominee C.M. Chan, and award-winning author Jo Ann Ferguson. Previously, she worked as a bookseller for Waldenbooks, and also for Forbidden Planet, the retail division of London's Titan Books.
