Perseus Spur. An Adventure of The Rampart Worlds

From Julian May, the acclaimed author who created the incredible worlds of The Many-Colored Land and The Golden Torc, comes a bold new science fiction adventure!When rebellious Asahel Frost was expelled from the Interstellar Commerce Secretariat on trumped-up charges, he lost it all: wife, citizenship, fortune, self-respect. Exiled to a beautiful but remote planet in the Perseus Spur, Frost became Helmut Icicle, a man without a past or a future.
But someone remembered Asahel Frost--remembered him enough to send an assassin to kill him. And in so doing, brought him back to life. Now, determined to track down the would-be assassin, Helmut finds himself caught in a conspiracy as convoluted as it is deadly. His sister, Eve, has mysteriously vanished. His estranged father wants him to find her with the assistance of the lovely Matilde Gregoire, who happens to hate his guts.
As Helmut follows the tangled strands of deceit, greed, and violence back to their common source, he begins to wonder if he is the hunter or the hunted .
