Silo 49 - Ann Christy - Bog

Silo 49 has endured. In Going Dark they freed themselves from the WOOL agenda. In Deep Dark they discovered their forgotten past. In the third installment of the Silo 49 series, all that they have worked for through the generations finally comes to fruition. The dawn is near and the long dark is finally ending.
Lillian and Leo - cousins and best friends - enter the lists for the 89th Race in Silo 49. The prize they seek is the singular honor of running outside, with no boundaries and no walls to hem them in. But the run is much more than a simple, but risky, trip outside to map their surroundings. The silo is falling apart, age and wear showing in every crack and seam. If the Others will not die out and let the world be reborn, then they must seek a way around the Others and find the blue skies for themselves.
