Showing Running Blind by Shirlee McCoy

The mission trip to Mexico was supposed to be an adventure.

But the thrill turns sour when Jenna Dougherty and her roommate Magdalena are kidnapped. A head injury leaves Jenna temporarily blind, with no hope of escaping or helping her friend…until Nick Jansen arrives.

The ex-marine brings Jenna safely home to doctors who restore her sight - but she opens her eyes too late to save her friend. Nick helped her before - can he help her find Magdalena's killer? Or will chasing this trail have Jenna running blindly again into danger?
