The world has finally seen Lethias as the gorilla he is and it wants him gone.

With zealot Melissa Adenour ascending to the Vice Presidency and the Oregon Initiative becoming law, Lethias wants only one thing: to return to the island. To return to his people. To return home. But standing in the way lies hundreds of miles of back country and a land that has decided who he is and what he deserves.

As LeRoy Parkin's company, LifeWorks, where the apes were created, crumbles under legal assault and the island's location grows harder to protect, a scientist's impossible physics points toward solutions no one anticipated. The gorilla, Jefferson, has taken these field equations further than any human can follow. And a mysterious being called Arthur has been waiting-patient, enormous, purposeful-for exactly this moment.

The final volume of the Brother to Jackals trilogy brings its characters to a reckoning that is by turns heartbreaking and triumphant, asking what home truly means when the world you were born into no longer wants you.

Some journeys begin as exile. Some end as legend.
