Light is big business on Evig Natt, where it's always dark and fireflies are the only legal source of light. They’re also used for currency, leaving the impoverished to live in the shadows of the wealthy. Severum Rivenshear is hired by the government to stop the Kontractor, a woman speeding the planet's rotation to bring light to rich and poor alike, until his beliefs and life shatter while witnessing the abuses of power. Together, their journey will take them from space to cyberspace, from reality to virtual reality, as they save the last refuge of humanity. In a time of war, they must bring balance to the hemispheres, even if Severum must betray the very system he’s sworn to protect.

Inertia revolves around the connection between government factions, big corporations, and the environmental destruction they create for their own profits. A young geophysicist, Ash, finds herself at the nexus of all this as she infiltrates servers in virtual reality to discover the hidden connections, but with the Enforcers on her tail, she can't do it alone.
