'The Song of Albion' is a trilogy of fantasy novels by American writer Stephen Lawhead, consisting of 'The Paradise War' (1991), 'The Silver Hand' (1992) and 'The Endless Knot' (1993). "The Song of Albion" trilogy was a series of books set between the Celtic Otherworld and present-day Britain.

The series combines Christian religious themes with Celtic mythology and tells the tale of a pair of university students who stumble into an alternate world (Albion). It has been continuously in print for over twenty years and remains one of Lawhead's most popular series.

Stephen R. Lawhead (born at Good Samaritan Hospital, Kearney, Nebraska on the 2nd of July 1950) is a UK–based American writer known for his works of fantasy, science fiction, and historical fiction, particularly Celtic historical fiction. He has written over 28 novels and numerous children's and non-fiction books.

In 1981, Lawhead began to author novels, initially fantasy and science fiction, completing his first trilogy, the "Dragon King trilogy". In 1986, he moved to Oxford, England to do research for The Pendragon Cycle, a reinterpretation of the legend of King Arthur in a Celtic setting combined with elements of Atlantis. Heavily rooted in the original Celtic source material which gave rise to the later and more familiar versions of the Arthurian legend, the series has received critical acclaim for its creative retelling of the Arthur legend and historical credibility.
