Like everyone born after The Shift, sixteen year-old Aura can see and talk to ghosts. Persistent, and often angry, some even on the verge of becoming Shades, these violet-hued spirits are constantly talking to her, following her, and demanding her help to make amends for their untimely deaths. Aura has always found this mysterious ability annoying and wished she could find a way to reverse it. She'd much rather the ghosts left her alone so she could spend time with her boyfriend, Logan. But when Logan dies suddenly and unexpectedly, Aura is forced to reconsider her connections with the dead and, the living. Surely a violet-hued spirit Logan is better than no Logan at all, isn't it? And things are complicated further when new exchange student, Zachary, is paired with Aura for a class project researching the 'Shift phenomenon'. Zach is so understanding - and so very alive. His support and friendship means more to Aura than she cares to admit. And, as Aura's relationships with both the dead, and the living, become more complicated, so do her feelings for both Logon and Zach. Each holds a piece of her heart and clues to the secret of the shift.
