Some melodies reach across the stars. In 2157, the Adryil—an advanced race of telepathic humanoids—contacted Earth. A century later, 15-year-old violist Iris Lei considers herself lucky to attend Papilio, a prestigious performing arts school powered by their technology. Born penniless, Iris’s one shot at a better life is to attract an Adryil patron. But only the best get hired, and competition is fierce. A sudden encounter with an Adryil boy upends her world. Iris longs to learn about him and his faraway realm, but after the authorities arrest him for trespassing, the only evidence she has of his existence is the mysterious alien device he slipped to her. When she starts hearing his voice in her head, she wonders if her world of backstabbing artists and pressure for perfection is driving her insane. Then, she discovers that her visions of him are real—by way of telepathy—and soon finds herself lost in the kind of impossible love she depicts in her music. But even as their bond deepens, Iris realizes that he’s hiding something from her—and it’s dangerous. Her quest for answers leads her past her sheltered world to a strange planet lightyears away, where she uncovers secrets about Earth’s alien allies that shatter everything she knows.

Sing your truth. Defend your dream. Defy your stars. A month has passed since Iris joined an underground rebel group to save Dámiul from the brutal prison he was sent to for fighting back against his world’s oppressive system. Here, conformity and compliance are enforced through telepathy, and Earthling performers are brainwashed into absolute obedience. Word of a merciless crackdown on those who sympathize with their cause leaves both Iris and Dámiul yearning for action. Determined to liberate her kind, Iris volunteers to return to her former patrons and covertly recruit supporters. A raid on their hideout catapults her plan into action sooner than expected and forces her to leave Dámiul behind. After persuading the authorities that she’d been telepathically manipulated into helping him, Iris assumes the role of a dutiful musician while secretly spreading whispers of a possible uprising among her fellow performers. But the authorities always seem to be one step ahead, and anyone who defies them is swiftly mind-wiped. Soon, Iris is forced to confront a horrifying fact: there’s a traitor among them. Desperately clinging to her cover, she races to find out who before her true loyalties are discovered—and the search leads her to an unthinkable answer.

When darkness falls, the stars ignite. Against all odds, Iris has made her voice heard. Inspired by her call for freedom, sympathizers to her cause have occupied a prestigious theater in the heart of Adrye’s capital. Their demands are simple: Abolish the cruel systems that use brainwashing to force obedience upon both Earthling performers and aberrant Adryil. Recognized as the face of the movement and caught in the thick of the demonstration, Iris finds all eyes turning to her. The authorities are determined to stamp out the nascent uprising. When new and unexpected allies arrive in time to keep the patrolmen at bay, Iris welcomes them. However, their addition sparks further unrest. Though she pleads for peace, others believe the only viable path is an all-out battle. Divided and under siege, the movement teeters on the brink of chaos. As the situation around her rapidly spirals out of control, Iris struggles to find a way forward—before the hope for freedom falls apart.
