Aria Davis's life has never been easy. Her mother and her best friend are the only people she has, and a tragic past looms behind her like a shadow. She isn't the only person suffering, either. Teens are vanishing left and right around her small town, for no particular reason at all. People are on edge. She thought things couldn't get worse. Until, one day, they did. She becomes one of the missing teens herself, and discovers why they have been disappearing. They have become candidates for The Game of Undesirables, an event held by an alien race of creatures called Tarmantii, where they are forced to complete impossible, lethal tasks or die trying. The last human standing will be taken back to Earth.
