For the tens of thousands of visitors to the world's largest theme park, the day begins with a smile. But by the end, they start to wonder if they will escape with their lives.

Undercover Delta Force operative Master Sergeant Jonathan "Jad" Bell has been deployed to act as the theme park's lead security officer. The threat begins with the announcement of a hidden dirty bomb but quickly becomes something far, far worse. Trained since the age of eighteen to save innocent victims from impossible hostage situations, Jad scrambles to assess the threat and protect the visitors. He will come face-to-face with a villain whose skills match his in every way—and present a danger Jad may not be able to stop.
