Big hitter Peter F. Hamilton sets his latest outing on a generation ship in search of a new world, where people are only allowed to live for 65 years so they don’t deplete the ship’s resources. When a teenager Hazel’s brother has an accident that means he is no longer productive, he is set to be killed off. She discovers that much of what the ship’s passengers have been told for the past 500 years is untrue. This is the first in a trilogy, all three of which will be published this year.
