The book is set in a not-too-distant future, in a community based on an oil rig, and it explores some interesting ideas. What happens when the very structure on which a society is built is owned and controlled by a company - and there's no easy way out? What happens when families have a planning horizon of centuries? What is the nature of absolute power?
The characters in the book are credible. The environments are detailed, and the world-building is credible. The story rattles along nicely - and the character development in the main protagonists is as interesting as the various plot twists.
