#1 New York Times bestselling author Daniel Silva’s celebrated debut novel, The Unlikely Spy, is “A ROLLER-COASTER WORLD WAR II ADVENTURE that conjures up memories of the best of Ken Follett and Frederick Forsyth” (The Orlando Sentinel). “In wartime,” Winston Churchill wrote, “truth is so precious that she should always be attended by a bodyguard of lies.” For Britain’s counterintelligence operations, this meant finding the unlikeliest agent imaginable—a history professor named Alfred Vicary, handpicked by Churchill himself to expose a highly dangerous, but unknown, traitor. The Nazis, however, have also chosen an unlikely agent. Catherine Blake is the beautiful widow of a war hero, a hospital volunteer—and a Nazi spy under direct orders from Hitler: uncover the Allied plans for D-Day...

The city states of the Lowlands have lived in peace for decades, bastions of civilization, prosperity and sophistication, protected by treaties, trade and a belief in the reasonable nature of their neighbors. But meanwhile, in far-off corners, the Wasp Empire has been devouring city after city with its highly trained armies, its machines, it killing Art . . . And now its hunger for conquest and war has become insatiable. Only the aging Stenwold Maker, spymaster, artificer and statesman, can see that the long days of peace are over. It falls upon his shoulders to open the eyes of his people, before a black-and-gold tide sweeps down over the Lowlands and burns away everything in its path. But first he must stop himself from becoming the Empire's latest victim.

Join Godfrid the Dane for murder and mayhem in medieval Dublin! Godfrid the Dane makes his first appearance in the Gareth & Gwen Medieval Mysteries in the first book, The Good Knight. He comes to Anglesey at the behest of the treacherous Prince Cadwaladr, but quickly realizes the deal he’s made is not quite what he thought, and Cadwaladr is not worthy of his allegiance. He takes it upon himself to learn the truth about what is going on in Wales and in the process encounters a young Welsh woman, Gwen, and her fiancé, Gareth, who comes to Ireland in search of her. Godfrid and Gareth grow to respect each other, and Godfrid returns to Gwynedd in The Fallen Princess, on a quest to find the Book of Kells, which has been stolen, and again in The Lost Brother, in search of allies in his conflict with Ottar of Dublin. In both instances, he ends up aiding Gareth and Gwen in their investigations. By 1148, when The Viking Prince opens, Godfrid’s dispute with Ottar, the King of Dublin, has reached a critical moment. Years earlier, Ottar usurped the throne of Dublin, depriving Brodar, Godfrid’s older brother, of his birthright. As the summer solstice approaches, Dublin is shocked by the murder of a prominent merchant, but only Prince Godfrid knows that the dead man was also a co-conspirator in his brother's plan to take the throne of Dublin. With death stalking his every move, Godfrid must call upon new friends and old to find the killer—and, with their help, uncover a conspiracy stretching beyond Dublin's walls to every kingdom in Ireland. The Viking Prince is followed by The Irish Bride.
