Ice Monarch by Michèle Laframboise

Transplanted into an immortal shell, Dominique roams over landscapes devastated by climatic changes. The giant monarch butterly records merciless wars erupting between pockets of survivors, for the pleasure of his masters, who dwell in lavish palaces rolling over the arctic sythetic ice.
The monarch is indestructible, as long as he flies in the rarefied altitudes, high over the people scraping a miserable existence from the scarred earth. but can he stay aloof when his masters condemn a village of smart, resourceful folks?

A compelling story of climate change and survival, told by multiple awards-winning Canadian SF author Michèle Laframboise.
