All Voi wants is to fly her plane and live a decent life, but something stands in her way: emelesia, a rare condition likely to land her in a mental asylum. Forever. Then comes Mr. Callahan, the mysterious agent who convinces Voi to spy for a cure. The catch? She has untapped elemental powers, and the enemy is psychic.

Desperate for a remedy, the aviatrix trains for a dangerous mission, wary of the person she's being molded into. The threat of coercion hovers constantly: become an elemental agent, or face the asylum. Meanwhile, Voi struggles with unusual side effects—from overwhelming urges to unintentional manifestations of her powers, due to unchecked emotions.

Between learning how to control her abilities, Mr. Callahan's growing reluctance towards her potential, and dealing with psychic revolutionaries... becoming an elementalist seems less and less appealing. Can Voi and her handler learn to trust one another, or will the machinations of paranormal politics lead to their undoing?
