NOT ALL PATIENTS CAN BE CURED—OR WANT TO BE. Visiting psychologist Carolyn Fern’s newest patient is Josephine Ruggles, an heiress whose nightmares leave glyph-shaped wounds across her back. Miss Ruggles’s case is unusual, even for an institution like Arkham Sanatorium. Her case takes an even stranger turn after she claims to have met Malachi—Carolyn’s former patient whose treatment was cut short when he was brutally murdered—in her dreams. When Carolyn uses hypnotherapy to address Josephine’s trauma, they find themselves both journeying to a strange place Josephine calls “the Dreamlands.” Together, Carolyn and Josephine discover that the mind is a powerful tool, but knowledge is dangerous. What is learned cannot be unlearned, and not everyone is prepared to pay the price.
