The Sword and the Stallion — Michael Moorcock

There is a sword, forged by the master swordsmith Goffanon the Dwarf, imbued with powerfully magical properties. But this magic can only be wielded by one man. And there is a stallion -- a fierce animal that allows only those pure of heart to ride it. The only man worthy of taking up this sword, and climbing into this saddle, is Prince Corum -- the Eternal Champion.

The struggle for dominion between the races of good and evil is reaching an epic crescendo, and the formidable Gods of Limbo threaten to deliver unending Chaos to the world. Corum's most desperate quest yet will see treachery, betrayal, wizards, dragons and brutal battle, all of which will decide the fate of the Earth, and of Corum himself.
