The Teir, a tiny machine powered by long-lost magic, has predicted the end of the world. Only two students from a prestigious university can stop it by mastering that same magic.

Malou Lamaire's biggest secret is that she can use what little magic is left in the world, but then she uncovers a plot to steal the Teir. So she steals it first and goes on the run to protect it from those who wish to use its power for their own gain.

Gavriel Eng, her willing accomplice, is accustomed to running from his secrets, but he can't run from his true identity any longer. Not when it requires him to seek an ancient, dangerous magic to make his own—and he's not the only one on the hunt for it, either.

Their combined power is the key to rooting out an evil that defies the laws of life and death—and their failure means the end of everything.
