Darksight by DC Mallery

Audra Carter, a popular deejay in Manhattan, won't let mere blindness keep her from living life her way, sometimes even riding her bicycle through town, relying on keen hearing and uncanny instincts to guide her. Her father, Jenson Carter, a neuroscientist, has devoted his career to finding a cure for her particular form of blindness. He now believes he has. With Audra and several other test subjects, Jenson takes his research to the next level, only to face apparent failure. Jenson becomes alarmed by several bizarre deaths involving the test subjects. He fears his experiment was hijacked by former colleagues with a secret agenda, but the police blame him for the deaths. Audra is kidnapped and forced to survive a series of terrifying ordeals designed to hone a new and dangerous kind of vision that the hijacked experiment unleashed: Darksight. As Jenson races to discover the truth and find his daughter, Audra struggles to survive increasingly-deadly challenges. Will Audra master her mysterious Darksight and defeat her captors to keep both her and her father alive?
