The Sleeping Sickness Spreads
New York City faces a terrifying epidemic: people are falling into an unresponsive, death-like sleep, called the 'sleeping sickness.' Doctors are baffled, and panic spreads. Evie O'Neill, now famous as 'America's Sweetheart Seer' after exposing a serial killer, enjoys her celebrity, though other Diviners find her self-absorbed. Unknown to most, the illness is linked to a malevolent entity that preys on dreams, drawing victims into a permanent slumber. The public and authorities are desperate for answers, but the true threat is known only to a select few with extraordinary abilities.
Henry's Dream Quest
Henry DuBois, a jazz pianist and dream-walking Diviner, is haunted by Louis's disappearance. He believes Louis is trapped in the dream world and searches for him nightly. Henry's dreams are vivid and dangerous, often showing him fragmented memories and unsettling premonitions of a growing darkness. He meets other dream-walkers and glimpses the rising threat without fully understanding it. His personal search for Louis connects with the larger mystery of the sleeping sickness as he realizes the dream world is becoming corrupted and perilous.
Ling Chan's Secret World
Ling Chan, a young Chinese-American girl in Chinatown, has the powerful Diviner ability to walk in dreams, a secret she guards closely in a prejudiced society. She attends a special school for gifted children, where she often feels like an outsider. Ling uses her dream-walking to explore, learn, and escape her waking life. She is aware of the dangers in the dream world, especially a growing malevolent force. Ling's journey is one of self-discovery and resilience, as she tries to understand her powers and her place in a world that often dismisses her.
Sam's Investigation and Evie's Distraction
Sam Lloyd, a charming and cunning Diviner, first dismisses the sleeping sickness, focusing on his usual schemes and trying to get Evie's attention. However, as cases multiply, Sam, with his photographic memory and street smarts, begins to connect clues. Evie, meanwhile, enjoys her celebrity as 'America's Sweetheart Seer,' attending parties and enjoying the spotlight. She is somewhat disconnected from the city's grim reality, much to her uncle Will's exasperation. This contrast shows how different Diviners react to the escalating crisis.
The Man in the Stovepipe Hat
A shadowy, sinister figure, later identified as the 'Stovepipe Man,' is the main antagonist. He is a powerful, ancient entity who manipulates the dream world, preying on sleeping sickness victims. His goal is to gather enough spiritual energy to fully appear in the waking world and unleash greater terror. He can possess individuals and subtly influence events, making him a formidable and elusive foe. The Diviners slowly uncover his plan, realizing the sleeping sickness is only a symptom of a larger, ancient evil, threatening New York and possibly the world.
Meeting in the Dream World
Henry and Ling, both dream-walking Diviners, independently navigate the dangerous dream world. They eventually meet, along with others who have similar abilities, forming an unexpected and uneasy alliance. They share information about the encroaching darkness and the terrifying entities they've seen. These encounters are dangerous, as the dream world is no longer safe but a battleground where the Stovepipe Man's influence grows. Their collaboration helps them understand the sleeping sickness and the true threat they face, as they are the only ones who can confront the evil in its own domain.
Theta and Memphis's Struggles
Theta, a showgirl and Diviner with psychometric abilities, is haunted by traumatic memories, especially of her abusive husband, who she believes is dead. Her powers, which let her see the past of objects and people, are both a gift and a curse, often overwhelming her with painful visions. Memphis, a poet and Diviner who can heal with words, uses his abilities to help his Harlem community, offering comfort to those affected by the sleeping sickness. Their personal struggles and moral compasses guide their actions, even as the city descends into chaos, showing the varied impacts of Diviner powers.
The Diviners Unite
As the sleeping sickness escalates and the true nature of the threat becomes clearer, the Diviners slowly begin to unite. Will Fitzgerald, Evie's uncle and the curator of the Museum of American Folklore, Superstition, and the Occult, helps bring them together, recognizing the ancient evil. Evie must set aside her celebrity and confront the grave danger. Sam's investigative skills, Henry and Ling's dream-walking, Theta's psychometry, and Memphis's healing powers all become essential for their collective defense. They realize that only by combining their unique abilities can they hope to stand against the Stovepipe Man.
Journey into the Lair of Dreams
With a clearer understanding of the Stovepipe Man's plan, the Diviners prepare for a perilous journey into the 'Lair of Dreams,' where the sleeping sickness originates. This is a dangerous task, as the dream world is corrupted and filled with the Stovepipe Man's minions and illusions. Henry and Ling, with their expertise, lead the way, while the other Diviners support them, using their powers to navigate the treacherous landscape and protect each other. Their mission is not just to find a cure for the sleeping sickness but to directly confront the ancient evil that threatens to consume both the dream and waking worlds.
Confrontation and Sacrifice
The Diviners finally confront the Stovepipe Man in his stronghold within the dream world. The battle is intense, requiring the full scope of their combined powers. They discover the true extent of his power and the horrifying sacrifices he demands. During the confrontation, difficult choices are made, and not all Diviners emerge unharmed. There are moments of heroism, betrayal, and loss. The climax sees the Diviners pushing their abilities to their limits, understanding that New York's fate rests on their ability to defeat this ancient, malevolent entity, even if it means making the ultimate sacrifice.
The Aftermath and Lingering Threat
After the battle, the immediate threat of the sleeping sickness is contained, and many victims begin to awaken, though some remain permanently lost. The Diviners, though victorious, are left shaken and wounded. They understand that while they have won a significant battle, the Stovepipe Man, or at least his influence, has not been entirely eradicated. The experience strengthens their bond and their understanding of their collective purpose. They realize that their fight against ancient evils is far from over, and they must remain vigilant, preparing for future confrontations as the world slowly comes to terms with supernatural forces.
