The Champion of Garathorm is the second novel in the The Chronicles of Castle Brass series by Michael Moorcock and featuring Duke Dorian Hawkmoon and Ilian of Garathorm. It is a sequel to both Count Brass and to the Erekosë novel Phoenix in Obsidian, and is followed by The Quest for Tanelorn....

Moorcock continues the Chronicles of Castle Brass with this odd little novel, perhaps one of the riskiest novels of Moorcock's career. Dorian Hawkmoon, united with his old friends, has paid a deep price-the loss of his wife and children. Or did he ever have them in the first place? Many at Castle Brass say he's been mad for the past five years, inventing the marriage and children after the death of his betrothed at the Battle of Londra (in the novel The Runestaff). Brought back to what they consider sanity by the arrival of a guest, an old friend of Count Brass', Hawkmoon feels that adventuring may be the best thing for him, and goes off into what is certainly the eternal champion's oddest adventure yet.

The oddities begin about a third of the way into the book, and explaining them would be impossible without major plot spoilers. Suffice to say that originally, the oddities seem as if Moorcock has just spliced together-badly-a series of unrelated stories. Such is not the case. Everything ties together, and as strand after strand comes full circle, the reader will get the idea of what Moorcock is on about. Once the whole weave is in place, the picture is staggering.
