"William Dietrich is a born stylist, moving characters around on an historical chessboard with the assured hand of a master novelist firing on all cylinders. Ethan Gage is a wiry, battle-scarred hero, with great decency, who rings absolutely true."
—Steve Berry, New York Times bestselling author of The Jefferson Key

"William Dietrich...should be read by anyone who loves adventure at its grandest, or humor both smart and sharp, or romance with a wild heart."
—James Rollins, New York Times bestselling author of The Devil Colony
