The World After the Fall, Vol. 4

A tower one day appeared in the skies, standing out as a beacon of chaos and apocalypse. A heroic and powerful lot known as Walkers cleared the tower floors in order to save humanity, until the day that the Regression Stone was discovered. Walkers could now "return" to the past, and slowly, everyone left. The brave few who remained formed Carpe Diem, a group of people who refused to abandon the world and represented humanity's last hope. But once the last Walker reached floor 100, he no longer knew what to believe... A new series from the creative team behind Omniscient Reader.
