Gavin Guile found his illegitimate son, the former fiancée discovered Prism's most terrible secret, and magic is going out of control all over the world. An army of color mages, worshipping ancient gods, is ready to join in the destruction of the Seven Satrapies.

But worst of all, Prism has not five years left to live, but less than a year. Gavin Guile is dying.

And the only one who can save the world is Gavin's devoted brother.
