The book deserves 4 stars for renovating old tropes:
>Hollowed asteroids for human habitation. The shell of this asteroid doesn't spin, but an inner spindle of cities creates centripetal force.
Prospectors bringing in metals, water, and fuel frozen in the asteroids. Once on Phoecea, they are reduced to atoms for re-assembly.
Modifications to the human body. Improved eyes. Neon tattoos as women's makeup. Beings who artistically modify their own DNA.
>Extending networking technology to incorporate virtual reality, conferencing (or conversely, privacy bubbles), AIs as personal assistants all via neural implants. If that can be done, then hackers will also tap into your head.
I gave 5 stars for:
>Characterization. Jane is an older bureaucrat, accustomed to walking a tightrope. Her department disassembles waste and scrap to make new assemblies. It handles shipping, provides hydroponic food and power. Her home is in the asteroid belt where solar radiation is almost nil. The asteroid must buy ice/methane shipments to offset heat and oxygen losses. The balancing act requires her constant attention.
Geoff is a talented guy who fails to measure up to his older brother. When not in school, he chills with three other friends, trying to delay that time when they must become contributing members of the colony. Like others, he thinks nothing of riding out to his own asteroid.
Viridians, modified humans, dealing with rejection and discrimination but still available when the colony needs them.
>Imagery of asteroids- the dust and irregular surfaces, their veins of silica and metals, and measuring their gravity to calculate density. All from up close and personal, not from the safety of a ship.
>The thought of a colony signing a contract to allow tiny broadcast cameras to follow anyone for broadcast back to earth as entertainment. This is a major issue throughout the story.
>Dialog- a necessary part of storytelling and Locke does it well.
Now, for the second book of a trilogy?
