Double Blind Hardcover by Iris Johansen

Kendra Michaels, formerly blind and now a hired gun for law enforcement agencies who relies on her razor-sharp powers of observation, is reluctant to help the FBI with the most recent case they've brought to her. But then she hears the details: the body was found just blocks away from Kendra's condo. The young woman was carrying an envelope with Kendra's name on it, and inside was an SD card with what appears to be an innocuous video of a wedding reception. The woman died trying to get the video to Kendra, but for what purpose? Before Kendra and the FBI can answer that question, the bride is abducted from her suburban home.

And so the hunt is on for a killer whose nightmarish plan is slowly becoming clear. A plan that involves a powerful law firm and a multi-billion dollar corporation. As the body count rises, Kendra joins forces with private investigator Jessie Mercado and agent-for-hire Adam Lynch to stop the plot as it grows ever closer to its terrifying conclusion.
