From publisher blurb:
Sometimes, when it rains in a Wyld-touched area in the Northern Threshold while the sun shines, chaos taints the clouds, turning a normal sun shower into a Wyld one. The altered rain burns where it lands, not with flame but with searing heat. The storm scorches crops and severely burns anyone caught in the deluge. Even after the skies clear, a secondary threat lurks in puddles of pooled light.
When a person or animal drinks of the liquid sunlight, their core catches ablaze. Light coruscates from every orifice as their body sizzles and steams. The false sunlight boils away their minds and personalities, until all that remains is the haloed husk — a being of pure radiance and raw instinct wrapped in its still-living flesh. Some people nickname these creatures “sun dogs,” as their most common forms in human settlements are those of beloved pets turned monstrous.
