'The Office' secretary gets a book deal

"The Office's" Ellie Kemper -- better known as receptionist Erin Hannon on the show -- has sealed a deal with Three Rivers Press to co-write a comedic novel with her sister, "The Office" writer Carrie Kemper. (Above, that's Ellie on the left and Carrie on the right.)"Monday Sessions" will center on misplaced diary entries and patient progress notes belonging to single New York therapist Dr. Amy Rice. The entries and notes get more idiosyncratic as Dr. Rice gets inappropriately involved with her clients.

“We are hoping that this is only the first in a series of Kemper-family manuscripts," Ellie Kemper said. "We know that our two brothers are eager to get their own book, Ellie and Carrie: The Worst People In Our Family, off the ground as well.”

Book will be published in spring 2012. Three Rivers Press is an imprint of the Crown Publishing Group at Random House.

"This is the first book we’ve ever written," said Carrie Kemper. "And it’ll be like the tenth book we've ever read. So we’re very excited.”

The Kemper sisters grew up in St. Louis. Ellie Kemper's other gigs include serving as a contributing writer for The Onion, The Huffington Post, and McSweeney's Internet Tendency.
