Human healer, Isla buries her grief in her work until an incurable new illness begins to claim lives faster than she can save them. Vaelin, a guarded fae warrior, watches in vain as the same illness decimates his own people, twisting and turning their magic against them. When an ancient vision points him to an unremarkable human healer as their salvation, he embarks on a single-minded mission.

Vaelin is everything Isla resents — emotionless, entitled, and a member of the same fae court she holds responsible for her parents’ deaths. But when he arrives in her village insisting that she is the only one who may be able to cure the illness ravaging the continent, she realizes that the only way to help her people is to find the cure that could save them all.

Together, Vaelin and Isla race against time, navigating treacherous, unforgiving realms to seek the mysterious Seers who are their last hope for finding a cure to the deadly illness. Strange phenomena erupt across the continent: the earth shudders as natural disasters rip through the realms, magic revolts against its wielders, and old wars ignite with renewed bloodshed. Soon, it becomes clear the illness is but one symptom of something ancient and inevitable, a calamitous reckoning that was always meant to break the world — and Isla and Vaelin stand in the eye of the storm.
