The start of a brand new trilogy from the NEW YORK TIMES bestselling author of THE WAY OF SHADOWS. Gavin Guile is the Prism, the most powerful man in the world. He is high priest and emperor, a man whose power, wit and charm are all that preserve a tenuous peace. But Prisms never last, and Guile knows exactly how long he has left to live: five years to achieve five impossible goals. But when Guile discovers he has a son, born in a far kingdom after the war that put him in power, he must decide how much he's willing to pay to protect a secret that could tear his world apart.
