The plot, about a modern day man inexplicably sucked into a parallel world of sword and sorcery, sounds like typical pulp fanatasy hokum. Fortunately, it is far from being that. John Daker becomes Erekosė, the Eternal Champion, destined to forever wander the worlds of the multiverse as a pawn in the battle between law and chaos. What makes these three volumes fascinating however, and raises them above the level of similar books, is Moorcock's focus on the psychological torment of his hero.
This is some of Moorcock's earliest writing, and, lacking in the complexities of his later work, it is an easy and enjoyable read.
