What should've been a typical night at the local mall for Rory Emerson and her two best friends proved to be anything but when their city became host to a grim, foreboding ship suspended in the sky. When the town is invaded, Rory gets captured and wakes up alone behind unfamiliar bars. After meeting Parker, the dark haired, mysterious boy locked up next to her, she learns that she's been abducted onto the ship that remains above her home. In a race against time, Rory and Parker team up to break out and to get her back on Earth before it's too late or before she has no choice but to discover the true reason the ship's ruthless Leader, Heath, has taken her. But can Rory truly trust Parker? Despite his alluring eyes and knack for saving Rory, she is still unsure of whether or not he is even human. Without a choice Rory will do whatever it takes to get back to her family and friends. Even if that means ignoring the new truths she learns while upon the ship that make her question everything she thinks she's ever known.
