Smiling Faces (2011)

From Introduction:

The village of Kyrste, nestled peacefully in the foothills of the Throal Mountains, is well known in the region for its friendly people and hospitality. But Kyrste harbors an ancient, pre-Scourge secret. Every year on the Summer Solstice, the townsfolk sacrifice travelers to unknown forces in an ancient temple beneath the town square. The strange, organic, hive-like tunnels beneath the town suggest that this is not the work of Horrors, but something far more subversive.
