(Warning: This description -- and the story itself -- contain spoilers from Hugh Howey's Wool Omnibus.)

What happens when a silo goes dark -- willingly? Maya has been sent to Silo 23 to investigate. Disconnected from the grid, the silo appears to be dead, rotted from the inside. What Maya finds is a silo that is anything but deceased.

Shut off from the outside world and other silos, Silo 23 has evolved into something unexpected, and something more fearsome than Maya could have anticipated.

Greatfall: Part 1 is the first installment of Jason Gurley's dark serial novel, inspired by the world created by Hugh Howey in Wool.
