Eryn is the greatest hero the Community has ever trained. When a priest foresees that she and her guardian will save the Community, it seems like Eryn's future is assured. But when she loses her guardian on their first mission to gather the ichor that maintains the life-preserving dome over the Community, Eryn is stuck with Rina, the worst-ranked guardian. Things get harder as Eryn's resentment turns to love. Heroes don't fall in love with their guardians. It's supposed to be the other way around.

Rina has spent her entire life trying to prove that shadows don't always lie. She fights her unconditional love for her hero rather than accepting it as she is supposed to. When Rina discovers that the corruption of the Dark Lands may not just be outside the dome but also in the Community's system itself, Eryn is the only person who might listen. But will Eryn accept that the Community she loves so dearly is causing the destruction Eryn was prophesied to fix?
