The Ancient Magus' Bride: The Boy From the West and the Knight of the Mountain Haze

A lightning strike has damaged a magical stone monument. When the Wild Hunt, a mystical troupe of fairy riders, awake from their slumber as they do every few decades, they can no longer be subdued by the stone’s lack of magic. Thus, they scatter in all directions to spread death. Spriggan, the envoy of the fairy queen Titania, instructs Elias Ainsworth to track down the broken piece of the monument and unite it with the wild hunt. (anisearch.com)
