For a limited time, meet bestselling author Steve Martini's hero Paul Madriani in this special, discounted digital edition of Guardian of Lies, including excerpts from The Rule of Nine and Martini's forthcoming Madriani thriller, Trader of Secrets (available May 31).

In Guardian of Lies, fate has bound attorney Paul Madriani to a young Costa Rican woman accused of a horrific crime, ensnaring them both in a frightening conspiracy that ranges beyond U.S. borders. A Cold War nightmare is being reshaped for a new century—a threat too terrible to imagine yet too real to be ignored—leading Madriani, his partner Harry Hinds, and the fugitive Katia directly into the path of an unstoppable, very angry assassin. From the halls of American justice to the jungles of South America and a dark secret buried since the days of Castro's ascendance, the race is on to prevent the unthinkable—by unveiling the hidden truth protected by the "Guardian of Lies."
