The Holy One has ascended.

He annihilated the Palace occupants and defeated his daughter in the Trench. With no one left to stop him, the Holy One breached the Lost Library, sealing the portal behind him. His path to godhood is guaranteed, and when he inevitably emerges, he will be unstoppable.

Despite everything, Rose refuses to give up. Having traveled back in time, she seeks to level the playing field by learning the Adamic language. In the process, Rose will discover the man her father was and confront the creation of a monster.

Arriving in the past, Matt adopts a mission of his own—assassinating the Holy One before he can rise to power. If successful, Matt will change the course of history, but before his plan can be realized, Matt must infiltrate the Order of the Firstborn and help orchestrate its downfall.

The stakes have never been higher, nor the odds more grim, in this epic conclusion to The Adamic Trilogy. Matt and Rose will do the impossible to rectify the world, or they'll die trying.
