In her annual holiday letter to staffers, Simon & Schuster CEO Carolyn K. Reidy singled out the Children’s division for achieving its best year ever.

Here’s more from the letter: “Our Children’s Publishing division is booming and their results this year are the strongest in their history.  Much of the groundwork they have laid is now paying off, and the strength of their publishing, in particular in the teen, fantasy and middle grade categories with authors such as Cassandra Clare, Rachel Renee Russell, Becca Fitzpatrick and Thomas Sniegoski, is indicative of their ability to adjust to and benefit from the quickly changing tastes of our younger reading audience.”

The letter also noted that the publisher counted 154 New York Times bestsellers in 2010, with 14 titles climbing to the number one spot on the list. In addition, the publisher celebrated 15 titles on the New York Times Book Review’s 100 Notable Books of the Year.
