Layna Emery has spent her junior year trying to outrun the shadow of her psychiatrist’s shattering diagnosis. While her classmates plan for college, Layna wonders if she will make it to senior year before her reality unravels completely. She hasn’t even confided in her two best friends. For the first time in her life, she is utterly alone. Then, just before summer break, Layna has a particularly unsettling nightmare. In it, she and a sophomore named Blake witness the brutal murder of a classmate. As usual, Layna tries to bury the haunting images her mind conjured. But the truth emerges with the morning news. Her classmate is dead. Everything she saw was real. When Blake admits to having the same dream, Layna starts to question whether she really is losing her grip on reality. Or could she be gaining a grip on a new one? In a desperate search for answers, Layna and Blake leave the suburbs of New Jersey and find themselves descending into the underworld of the Oneironauts. The ancient Order is fighting to prevent a cosmic war for the life of the universe. A life that is soon prophesied to come to an end. Now, Layna and Blake must accept that dreams, their lives, and the world are not at all as they once believed.
