After the introduction of Yellow magic in a society accustomed to only Red and Blue magic, the world inside the barrier has become more complicated than anyone imagined. Ava, Elm, and the former students of Prism navigate life in hiding. They face discord, secrets, betrayal, and danger that looms ever closer as the Benefactors narrow in on their hideaway.

Ava is determined to keep everyone protected, even at the cost of her own safety. She explores dangerous aspects of her new Mentalist abilities--against Elm's dire warnings.

Tensions escalate when a new visitor arrives claiming to know a way out of the barrier. While this may be the only way to escape the Benefactors, what awaits them on the outside? Will they gain allies or make an entirely new set of enemies?
