The United States has always been a nation of immigrants - never more so than in 1917, when the nation entered the First World War. Of the 2.5 million soldiers who fought with U.S. armed forces in the trenches of France and Belgium, some half a million - nearly one out of every five men - were immigrants.

In The Long Way Home, David Laskin, author of the prize-winning history The Children's Blizzard, tells the stories of 12 of these immigrant heroes. Starting with their childhoods in Europe, Laskin unfolds the saga of their journeys to Ellis Island, their struggles to start over in the land of opportunity, and the ordeal of their return to Europe in uniform to fight - and win - a war that had already killed tens of millions.

Three of these soldiers died on the battlefield; two won the Congressional Medal of Honor; all were transformed forever by their experiences in combat. It is a transformation that continues to be felt in the pride and pain and cherished memories of immigrant families that have long since assimilated.

In tracing the lives of these 12 men, Laskin tells the story of an immigrant generation - a generation that streamed into this country in unprecedented numbers around the turn of the last century, that sweated to support their families through back-breaking physical labor, and that fought loyally for their adopted country on the battlefields of Belleau Wood, Soissons, St. Mihiel, and the Argonne forest. Based on stories, letters, and diaries passed on by descendants - as well as Laskin's personal interviews with two foreign-born Doughboys who were still alive at the time he was researching the book, The Long Way Home is a reverent work of history and a deeply moving evocation of the dreams and sacrifice at the heart of the American experience.
