Aura can see ghosts. Born after the Shift, a little-understood event that enabled younger generations to communicate with the dead, Aura is relentlessly pursued by these violet-hued spirits. They need help to pass out of this world and into the next. And some are so angry they are on the verge of becoming Shades, dark vortexes of energy. But Aura just wants the ghosts to leave her alone so she can spend time with her boyfriend, Logan.
When Aura is paired with a new foreign-exchange student to research the Shift for a class project, she is determined to ignore her partner's sexy Scottish accent and discover the cause of the Shift so she can reverse it.

Then Logan dies a most untimely death. Forced to reconsider her relationship with the living and the dead, Aura is caught in a love triangle with her violet-hued boyfriend and her hot research partner... one of whom may hold the key to reversing the Shift.
