Two years later, Impeached: The Trial of President Andrew Johnson and the Fight for Lincoln’s Legacy, was a Davis-Kidd Bestseller and was called “by all means the best account of this troubled episode” by Professor David Donald of Harvard. His first novel, The Lincoln Deception, about the John Wilkes Booth Conspiracy, was called the best historical novel of 2013 by Bloomberg View. In February 2015, Simon & Schuster released his latest nonfiction book, Madison's Gift: Five Partnerships that Built America.
