Heroes Die, Paperback

Renowned throughout the land of Ankhana as the Blade of Tyshalle, Caine has killed his share of monarchs and commoners, villains and heroes. He is relentless, unstoppable, simply the best there is at what he does.
At home on Earth, Caine is Hari Michaelson, a superstar whose adventures in Ankhana command an audience of billions. Yet he is shackled by a rigid caste society, bound to ignore the grim fact that he kills men on a far-off world for the entertainment of his own planet--and bound to keep his rage in check.
But now Michaelson has crossed the line. His estranged wife, Pallas Rill, has mysteriously disappeared in the slums of Ankhana. To save her, he must confront the greatest challenge of his life: a lethal game of cat and mouse with the most treacherous rulers of two worlds . . .
