About the Agency

Founded in 1976 by Barbara Lowenstein, Lowenstein Associates is a full-service agency that represents a diverse group of writers, including authors of acclaimed commercial fiction, cozy mysteries, thriller and crime fiction, middle grade fiction, narrative nonfiction, and exceptional literary and upmarket fiction; prominent cultural icons; and leading experts in medicine, psychology, and contemporary issues.

We have a unique approach to selling books and handling our authors’ careers, combining the kind of personal, hands-on attention of a boutique firm with the strong negotiating power of a corporate agency.

Our notable authors include Ishmael Reed, Carla A. Harris, Gordon Thomas, and M. C. Beaton, whose Agatha Raisin and Hamish Macbeth mystery series, as well as 99 Regency romance novels, have sold over 25 million copies worldwide. Beaton’s books have been translated into 18 languages and she is a bestselling author in the U.S., U.K., France, and many other territories around the world. Agatha Raisin has been adapted as a hit series on Acorn TV and Sky Max, starring award-winning actress Ashley Jensen. Season 4 premiered in 2022 and a fifth season is in development. M.C. Beaton’s bestselling Hamish Macbeth series will also be adapted as a TV series from the same producers as Agatha Raisin
