The Ptolemy Project

Four Teams. One Test. No Way Out.

Wake up, report to the tect, try to survive.

Life on Carcer Station is a change from the daily struggle of four strangers—Lyra, Zeke, Aquila, and Pollux.

As Children of Titan, the first generation born on Saturn’s colonized moon, they’re used to following rules. But when they wake up on an empty space station with no memory of how they got there and no one in charge, the ghosts of their past scratch their way to the surface.

Then things start to go wrong. The power in Carcer Station shorts out, and the veil around them thins. The four must fight to stay alive inside a system that’s falling apart as quickly as their own minds.

Even if they can make it out, will they be able to find a way back to Titan and to a society that accepts them—scars and all?
