Perfect for you if...

  • You enjoy hard science fiction grounded in near-future economics and engineering rather than fantastical tech.
  • You appreciate character-driven stories where personal vendettas drive the plot as much as the high-stakes business deals.
  • You're drawn to stories about independent operators and scrappy underdogs fighting against monopolistic corporate power.

Maybe not for you if...

  • You want standalone novels. This is book nine in a series and assumes familiarity with prior characters and events.
  • You prefer action-heavy plots over slow-burn character development and boardroom intrigue.
  • You're looking for romantic subplots to be central. The love triangle here plays second fiddle to the business conflict.

About this book

Following the death of visionary space industrialist Dan Randolph, his protégé pilot Pancho Barnes takes a seat on the board of his conglomerate. She faces significant challenges, particularly from Randolph's rival Martin Humphries, who seeks to control Astro and eliminate independent asteroid miners like Lars Fuchs from business. Humphries also pursues personal vengeance against Pancho and aims to reclaim Amanda, who is now married to Fuchs. The novel features memorable characters navigating human conflict, rugged high-tech prospectors, and boardroom betrayals. It continues the story of competition over the Asteroid Belt's vast mineral wealth in the near future. The narrative explores the consequences of this struggle, with some characters dying while others achieve unexpected success.
