Once all Roads led to Rome.
Now they lead to Ceres.
The dwarf planet Ceres, once thought of as little more than the biggest rock in the asteroid belt, has become humanity's most populated world in the years since Moses' departure. The desperate and needy of the solar system end up in syndicate run cities far beneath the surface. Few ever see the light of the stars.
The crew of the Sparrow, chasing rumors of a long lost piece of technology, turn to Ceres and find it stands on the brink of the abyss. Powerful crime groups are ready to go to war over old grudges and a misanthropic terrorist aims to use the chaos for his own ends.
In the midst of all this, Grace Anderson finds herself separated from Davey and stranded on the very streets they grew up on. Despite being the youngest member of the crew, she's not without her own part to play in the fates of Ceres, but that's only if Matthew and his crew can stop the world from tearing itself apart...
