From bestselling and award-winning author Cadwell Turnbull comes A Ruin, Great and Free, the stunning conclusion to the popular Convergence Saga. It has been nearly two years since the anti-monster riots. The inhabitants of Moon have been very fortunate in the intervening months. Inside their hidden monster settlement, they’ve found peace, even as the world outside slips into increasing unrest. Monsters are being hunted everywhere, forced back into the shadows they once tried to escape from. Other secret settlements have offered a place to hide, but how long can this half-measure against fear and hatred last? Over the course of three days, the inhabitants of Moon are tested. The Black Hand continues to search for them and the Cult of the Zsouvox wants to make Moon the last stand in their war against the Order of Asha. This is more than enough to reckon with, but the gods have also placed their sights on Moon—and they bring with them a conflict that may either save or unravel the universe itself.
