Mindsword's Story (6th Book of Lost Swords)

Long ago, the gods forged Twelve Swords of Power and threw them on the gameboard of life for men to scramble over. But they forged too well; the Swords could kill the gods themselves.

Now the great Mindsword reenters the world of men, bringing others' mindless devotion to him who wields it: Prince Murat of Culm, who intends to give it to Princess Kristin of Tasavalta. But first he draws it--and receives worship from his own son, from the princess herself, and from a horrifying "ally."

It is up to Prince Mark of Tasavalta: his wife and kingdom, and the world, all may be lost to the Mindsword.
