Crowley's Window by Gord Rollo
Abby Hawkins was never normal. Born with a birth cowl--a rare birth defect thought to predict psychic abilities--she is haunted by horrible visions. Shortly after her 13th birthday, Abby's parents call in the mysterious Crowley to help their daughter. His interventions rid her of the visions...and her eyes.
Now a beautiful young lady, Abby Hawkins works as a blind fortune teller in a traveling Carnival. When she receives a powerful vision--one depicting the abduction of a little girl--she becomes the sole witness to the crime. Only a young police officer believes her bizarre story, and with his help she embarks upon an investigation that will ultimately reunite her with the madman from her past and bring her to the hellish threshold of Crowley's Window.
