A fantasy series, by Katherine Kurtz, about medieval power politics in a world where there is a race of psychic humans: the Deryni. The first installment in the series was published in 1970, making it a relatively early example of modern fantasy, and one which is not modelled on Tolkien. The books were mostly published as a sequence of trilogies. In publication order, they are: * The Deryni Chronicles * Deryni Rising * Deryni Checkmate * High Deryni * Camber of Culdi * Camber of Culdi * Saint Camber * Camber the Heretic
