Greatfall Series by Jason Gurley

What happens when a silo goes dark? Maya has been sent to Silo 23 to investigate. Disconnected from the grid, the silo appears to be dead, rotted from the inside. But 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 horrifying than Maya could have anticipated.

The dark nature of Silo 23 continues to reveal itself to Maya, who lies bleeding and starving in a cell on the uppermost floor, and to Isaac, the innocent boy selected to carry on the silo's terrible legacy.

In Part 3, the longest installment of the series, Silo 23 is darker than ever before. While Maya and Esther flee into the down deep, Matthew subjects Isaac to the sort of rigorous conditioning that robs the boy of his soul. Daniel wrestles with his new identity, tormented by what he has learned. And the believers, just pawns in a centuries-long game, begin to learn the truth...In this pounding conclusion to Greatfall, thousands of people confront their nightmares... moreIn Part 3, the longest installment of the series, Silo 23 is darker than ever before.
