A group of teenage students, while exploring deep within the rainforest, barely survive an encounter with a wild and surprisingly magical boar. In doing so, they discover that events that threaten to destroy their entire civilization have already been set into motion.
The Black Tide, the annual rampage of millions of giant ants through the rainforest, has been coerced by the Demon Queen to take a path that will send it tearing through the farmlands that support the Citadel, their home.
While the adults frantically race to prepare for the coming disaster, one of the teenagers who survived the boar attack, Malcolm, begins to experience violent visions of the past. He learns that he’s no longer alone in his own body. His revelations lead the group of teenagers to discover that many of the leaders within the Citadel are similarly possessed.
After barely surviving the Black Tide and the demonic assault that followed, the group of newly possessed friends struggle to make peace with the willful spirits that inhabit them. While the spirits grant wisdom and power, it often comes at a terrible price.
Driven by her spirit's crippling guilt and sorrow, Eliana leads her friends on a dangerous journey across the jungle in a desperate search for answers. What happened in the Darkwood? What role did her spirit play in what transpired?
While the friends quest for understanding, the people of the Citadel struggle to rebuild and replant their ravaged farmlands. But hidden amongst them, an ancient demon carefully gathers power as she prepares to launch an assault against the magical painting that protects and preserves the Citadel.
