In the other, a forbidden love could forever destroy the resistance known as The Circle. Thomas Hunter can bridge both worlds, but he is quickly realizing that he may be able to save neither. In the surprising conclusion of the Circle Trilogy, Thomas must find a way to rewrite history as he navigates a whirlwind of events leading to certain apocalypse. The fate of two worlds comes down to one man's choice. Life. Death. Love. Nothing is as it seems. Yet, all will forever be transformed by one man in the final hours.
