Protocol Ashfall Book 4

by Karis Chan

One last ride. No return trip. The Directorate has fallen silent. Administrator Varin hasn't been defeated; he has retreated to the Nexus to initiate the final phase of Project Stability—a hard reset that will wipe free will from the gene pool. Aeryn Sol is done running packages. She’s done hiding in the dust. With a broken team and a bike held together by prayer and wire, the Ghost is riding straight into the heart of the machine. The logistical probability of survival is absolute zero. But Aeryn isn't riding for survival. She’s riding for the end.
