Brothers Istvan and Jensi grew up under the poorest dome on Vinduaga. Jensi has always looked after Istvan, who sometimes lashes out in sudden episodes of violent paranoia. When Istvan is sent offworld to a high-security prison, Jensi is determined to follow and find a way to keep his brother safe. But the prison guards a horrible secret, one that will push both brothers to the cusp of something much greater and darker than they ever imagined.
