Treasure hunters Peter Fallon and Evangeline Carrington are heading for adventure in Washington, D.C., the sleek, modern, power-hungry capital of America...and the crowded, muddy, intrigue-filled nexus of the Civil War. Their prize? A document of incredible historical importance and incalculable value: Abraham Lincoln’s diary.

What if Lincoln recorded his innermost thoughts as he moved toward the realization that he must free the slaves? And what if that diary slipped from his fingers in 1862? A recently discovered letter written by Lincoln suggests that the diary exists and is waiting to be found. Some want the diary for its enormous symbolic value to a nation that reveres Lincoln. Others believe it carries a dark truth about Lincoln’s famous proclamation - a truth that could profoundly impact the fast-approaching elections and change the course of the nation. Peter and Evangeline must beat these villains to the prize or risk a future that corrupts the vision for which Lincoln fought.

From William Martin, the New York Times best-selling author of The Lost Constitution, The Lincoln Letter is a breathless chase across the Washington of today as well as a political thriller set in our besieged Civil War capital. It is a story of old animosities that still smolder, old philosophies that still contend, and a portrait of our greatest president as he passes from lawyer to leader in the fight for the birth of a new freedom.
