This is the second book in Michael Moorcock's Chronicles of Corum series. The book continues the adventures of Prince Corum first begun in 'The Knight Of Swords'. In this book Prince Corum travels too a different plane to try and end the hegemony of The Queen of Swords, and thus save his own plane from the forces of Chaos. With him is the eternal companion of Champions,Jhary-a-conel and his winged cat.
I don't know if this story was originally written for a magazine format, but it certainly reads like it. This is probably the weakest of the swords trilogy, and like all three books in the sword trilogy, the pace is breakneck. One has no time to appreciate the dangers Corum finds himself in, before he is immediately rescued and moved on to the next predicament.
