Universal War One Revelations #1

Description

"The Purgatory Squadron’s survivors have done the impossible: By traveling through time, they’ve shut down the impenetrable Wall that divided the solar system. They’ve also discovered that the rebellious Colonization Industrial Companies’ hidden satellite in Earth’s orbit could destroy the planet. But the Purgatory Squadron, stranded three days in their own past, might be able to return to Earth without notice, giving the team of outcasts and criminals three days to stop a cataclysm that could bring about the first universal war."
