The classic novel that introduced the Deryni and launched Katherine Kurtz's career. In the land of Gwynedd, the Haldanes have long ruled and have long kept a dangerous secret: there are those of their blood who possess the magical powers of the Deryni. To be Deryni in a land ruled by the all-powerful Church is to be branded an outcast. But now, young Prince Kelson is about to assume the throne after the mysterious death of his father. He must be told of his magical heritage. For his legacy is being challenged by a woman who does not hesitate to lay full claim to her Deryni powers. And to face her in magical combat, Kelson must learn a lifetime’s worth of magic in a few short days. If he loses, he dies as his father did. And if he wins, he is King—but all the world will know that he is also Deryni…

More than thirty years ago, Katherine Kurtz changed the face of fantasy with the Deryni Chronicles. In 2005, Ace published a newly revised and expanded Deryni Checkmate in hardcover. Now, that edition is available in mass market for the first time.

In the conclusion of the Deryni series, political power meets its match in the power of magic as the time approaches for the king's wedding.

New York Times bestselling author of In the King's Service Alaric Morgan has been pledged to the king's service. His Deryni blood makes him ideal to safeguard the Haldane kings and ensure that Prince Brion shall have the protection of his hereditary magic.

Camber was the greatest of the Deryni who wanted to retire. But it was not to be. The kingdom of Gwynedd groaned under the tyranny of Imre and his sister and mistress, Ariella. And when Camber learned that Cinhil Haldane, a descendant of the previous kings, still lived, he was determined to set him on the throne in place of the evil ones....
