When seven people go missing from a dive boat found floating atop THE GREAT BLUE HOLE OF THE CARIBBEAN, there is panic to find them and learn their fate. When Angie Holland saw the story on National News, her blood ran cold. She feared the worst. "The bitch is back!" If she was right, she knew she must take action, immediately. To tell someone... anyone, the truth would do no good. Whoever she told would think she had gone over the edge. So, her mission was very personal. She had to go to Belize and finish what she thought was over two years ago. Twenty-four hours later, she was on a plane, bound for Central America. But questions abounded: What had gone wrong the first time? Why wasn't the siren dead? And if blowing holes in her with a bang stick didn't do the job, what would? As the plane jets south, Angie knows none of the answers. But she does know, this time, she must not fail. Untold lives depend on it for hundreds of years to come. And when it is over, nobody will know except her, and a small contingent who surrounds her.
