Something strange is happening in the mountains of Sanctuary.
Veterinarian Ember Burns makes a grisly discovery and it leads authorities to the body of a man in the woods above her home. Although the circumstances are suspicious, the only witness is her dog and the death’s ruled a suicide.
But things aren’t that simple. When Ember looks into the man’s local connections, it creates more questions than answers. Including the source of an unusual rock, and what he was really doing in the mountains.
As a mysterious illness sickens the local animals, Ember’s battle to save them leads to a startling discovery. She races to prove both the cause of the animals’ symptoms and how the man died, but will it be too late?
