Dr. Amal Robardin, a newly-licensed therapist who recently immigrated to Brooklyn from Beirut, is treating her first patient: Yasmin, who is schizophrenic. The two get off to a rocky start, and as Yasmins night terrors increase and the looming figure at the foot of her bed creeps closer every night, Amal begins to worry that shes out of her depth. Convinced that what she is experiencing is not a delusion, Yasmin becomes obsessed with Robert Chambers The King in Yellow. Messages she finds in the book lead Yasmin to flee her home, seeking answers she cant find in therapy. Distraught over Yasmims sudden disappearance, Amal attempts to retrace her patients last steps-and accidentally slips through dimensions, ending up in Carcosa, the King in Yellows realm. Trapped and determined to find her way out, Amal enlists the help of a mysterious guide, but is he a friend or her tormentor?
