Chasm City by Alastair Reynolds

Chasm City by Alastair Reynolds, Science Fiction --524 pages.
Tanner Mirabel must hunt down Argent Reivich and kill him to avenge the killings of Gitta, the woman Tanner loved, and her husband, Cahuella, Tanner's boss. Missing him in one attempt before Reivich gets off-planet, Mirabel must travel through space, sleeping for 15 years, to track him down. As he enters Chasm City in the final phase of the hunt, Mirabel discovers things about himself that don't add up(he can see in the dark, he seems to have never had his foot amputated), that lead him to wonder who he is and who is really being hunted. Long, but never dull, it ends on the kind of note that lets you know its part of a series. Patrick
