A bookseller never meant to wield magic. An archer who refuses to back down.

In a world divided between the floating city of Newfris and the untamed Earth below, Arra—a skilled archer, but no mage—fights for survival in the Muir Woods. While her sister Elanil wields the magic that Arra lacks, Arra battles the marauding Remnant, the last vestiges of a broken humanity. But when fate brings a group of rebels crashing from the sky, Arra's life collides with a deeper mystery.

Among the fallen is Trey, a bookseller with a hidden gift for magic, and Rylan, Phoenix's son, now fifteen and a mage himself. Together, they uncover a deadly plot by the Cothellon—dark elves with an apocalyptic device that could destroy the world. As Arra grapples with her own insecurities, she must join forces with these unlikely allies, all while her heart is pulled toward Trey in ways she cannot explain.

With time running out, Arra must prove that magic is not the only strength that matters. In a race against the Cothellon, the survival of Earth lies not in power, but in courage.

Can Arra rise to the challenge, or will the world shatter like the city in the sky?
