The novel “Chasm City” by Alastair Reynolds was published for the first time in 2001. It’s part of the Revelation Space universe. It won the British Science Fiction Association award.

Tanner Mirabel is a security expert who for years oversaw the protection of a powerful man on the planet Sky’s Edge and of his wife. When the two of them are killed, Tanner is taken by the lust for revenge and chases Argent Reivich, the instigator of the double murder, to the planet Yellowstone. That’s an inhospitable planet where, however, they built Chasm City, a habitat composed of huge shape-shifting skyscrapers. When he arrives, however, he discover that the city was devastated by an alien plague.
