Blink of an eye / Iris Johansen & Roy Johansen.

"Kendra Michaels was blind for the first twenty years of her life. Then she gained her sight through a revolutionary surgical procedure. Her former disability has left her incredibly observant and insightful -- able to detect what other investigators may not. So when a world-famous pop star is kidnapped mid-show, investigator Kendra leads a pulse-pounding race to rescue the young woman from a deadly foe. This time Kendra gets assistance from recurring character Jessie Mercado, a private investigator and army veteran who was the singer's former bodyguard. But as the abductor's true purpose becomes clear, Kendra and Jessie uncover a plot more terrifying than anyone could have imagined. They must beat the odds stacked against them before lives are lost and the predator's grand scheme is executed"-- Provided by publisher.
