Under the nom de guerre of Gar Pike, renegade psychic wizard Magnus D'Armand travels the stars fighting injustice and oppression, like his father, Rod Gallowglass, the Warlock in Spite of Himself. But this time the Rogue Wizard may have encountered a tyrant even he can't overthrow: a stern Protector who dictates the very thoughts of his "loyal" subjects. So successful if his regime that Magnus is hard-pressed to find anyone willing to oppose it--until a misguided handful of would-be aristocrats unwittingly provides a spark of rebellion. Here is Christopher Stasheff in top form: swashbuckling, stylish, and slightly subversive adventure from the author of the bestselling "Warlock" chronicles.

The hero is a professional liberator who roams space in search of oppressed peoples to liberate. He comes across a planet whose citizens are so oppressed they are not even allowed to think for themselves. Only thoughts which have been officially approved are allowed. So he organizes a revolution.
