Dr. Amal Robardin, a Lebanese immigrant and a therapist in training, finds herself out of her depth when her first client, Yasmin, a schizophrenic, is visited by a nightly malevolent presence that seems all too real.

Yasmin becomes obsessed with Robert Chambers’ classic horror story collection The King in Yellow. Messages she finds in the book lead Yasmin to disappear, seeking answers she can’t find in therapy.

Amal attempts to retrace her patient’s last steps―and accidentally slips through dimensions, ending up in Carcosa, realm of the King in Yellow. Determined to find her way out, Amal enlists the help of a mysterious guide.

Can Amal save Yasmin? Or are they both trapped forever?
