Harper Perennial and Harper paperbacks publisher Carrie Kania will depart, heading to London to serve as an agent at Conville & Walsh. Her departure also sparked a reorganization at the publisher.

HarperCollins has restructured the Harper Perennial and Harper paperbacks imprints, bringing them under the umbrella of the Harper and William Morrow divisions. Harper Division publisher Jonathan Burnham now oversees Harper Perennial. William Morrow, Avon, and HarperVoyager publisher Liate Stehlik will take control of Harper paperbacks.

Here’s more about the restructure, from the internal memo: “Cal Morgan will continue in the role of Editorial Director of the Harper Perennial paperback originals, reporting to Jonathan. Additionally, Amy Baker, Senior Director of Marketing, and Erica Barmash, Marketing Manager, will remain with the Harper Perennial imprint, reporting to Jonathan. Gregory Henry, Senior Publicity Manager, Anne Tate, Senior Publicist, Peter Henningsen, Assistant Publicist, will move over to Tina Andreadis, VP/Director Publicity. Michael Signorelli, Editor, will join the Harper editorial team.”
