Dan and Amy Cahill believed their family had won the hunt for the 39 Clues. The thirteen-year-old and his older sister thought the dangerous quest for ultimate power had ended in their favor. They were wrong. Distress calls flood in from across the globe. Family members disappear one by one, taken by a mysterious organization called the Vespers. The kidnappers issue a strange ransom demand with an impossible deadline. If Dan and Amy fail to deliver, their captured relatives will die. The siblings have no idea what the Vespers actually want or how to defeat them. One fact becomes clear as the deadline approaches. The Vespers intend to win at any cost, and if they obtain the 39 Clues, they will hold the entire world hostage. Dan and Amy must race against time to save their family and prevent global catastrophe.
