Seventeen-year-old Skylar has always been haunted by fleeting yet powerful feelings that something around her has gone wrong. Those impressions have never seemed to reflect anything real, and have only earned her stares and whispers behind her back. But after she meets a mysterious boy named Win, she learns an unsettling truth: we are not alone on Earth. In fact, visitors from beyond the stars are manipulating our planet and the essential fabric of our world; life as we know it is starting to unravel. And Skylar--and her heightened awareness--just may be the key to our salvation.
