Into Elysium by A.M. Johnson

About the Audiobook:

Eben had one job at Elysium–keep the barrier wall lit at all cost. As a Dusk Guard, he was safe from the war raging across the country, from the rebels, and the new world–safe from the battle over power, water, and electricity. He was safe from the laws that would see him dead if they knew his one secret. But when he’s called inside Elysium to watch over one of the rebel prisoners, every wall he’d created to protect himself comes tumbling down.

Cale never thought he’d survive the virus that had turned the world dark and had flipped his country upside down. He never thought his last days would be drawn out inside a cell in one of the most notorious prisons in the west. Elysium was a place for the dead. But in the pitch of night, the one person he’d thought he couldn’t trust becomes his savior and so much more.
