Andrew Carroll is the editor of several New York Times bestselling and critically acclaimed books, including Behind the Lines and War Letters, which inspired the PBS documentary of the same name. His most recent book is Grace Under Fire: Letters of Faith in Times of War.

Carroll is also the founder of the Legacy Project, a national and all-volunteer initiative that honors veterans and active-duty troops by seeking out and preserving their wartime correspondence. Since 1998, the Legacy Project has received an estimated 80,000 never-before-seen letters from every military conflict in U.S. history, including e-mails from Iraq and Afghanistan.

Carroll is also responsible as well for re-issuing the "Armed Services Editions" (ASEs), which are pocket-sized bestsellers and were first handed out to U.S. troops in World War II. Andy convinced publishers to revive them, and he has distributed a quarter of a million free ASEs to U.S. servicemen and women around the world, including thousands of books he personally handed out in Iraq and Afghanistan.

This month University of Chicago Press is releasing the paperback version of Operation Homecoming: Iraq, Afghanistan, and the Home Front in the Words of U.S. Troops and Their Families, which he edited on a pro bono basis.
