Batman: The Phoenix [Bruce Wayne/Batman x OC fanfic]

Symbologist and Iconologist Professor Vivian Pryor's dreams were crumbling as soon as they were about to come true. When the big step in her career begins with a public murder during her debut book launch, she finds herself being targeted by an unknown player who does not know, and to help her solve the case none other than Batman himself. But as he digs deep into the clues, he realizes that the forces in play are not Batman's regular costumed criminals. This is rare in Gotham. Magic. The only one who can help him solve this is the professor of symbology.

After dealing with the first case with Professor Vivian Pryor, Bruce Wayne finds himself drawn to the woman who too lives a double life. But unlike him who dons a bat costume and fights crime, Vivian's secret is beyond a mask. It deals with the sinister forces in the dark.
