Finding Famine

"Tyler Blythe is the youngest captain ever to be put in charge of a Doomship, kilometers-long warships whose power source extends the crew's lifespan but binds them to the vessel through physically addictive radiation. Tyler's people are the uhmani-a remnant of humanity that wanders the stars, sworn to maintain their ships, make no war for pride or religion, and above all to colonize no planet. But when a civil war within the Armada destroys the food-ship Famine and leaves the fleet on the brink of starvation, Tyler is charged with retrieving the scattered survivors of his own faction, including Nassir Redhook, the man who taught him what it means to be uhmani.
