World-renowned cellist Celeste Morgan has spent her life performing perfection on the world's grandest stages-while carrying out assassinations no government will ever admit to ordering. But when her mother's hidden files reveal the inner machinery of Eidolon, the shadow network that built her, Celeste becomes something far more dangerous than a weapon: a woman who knows where the bodies are buried.
Hunted across international concert halls and back corridors by former allies and a new, ruthless mastermind, Celeste must survive a brutal global tour where every performance could become her last. With her partner Kiril Volkov walking the razor's edge beside her, she is forced to confront a devastating truth: dismantling Eidolon may require becoming the very thing she despises.
As the music swells from New York to Tokyo to Barcelona and beyond, Celeste begins turning the organization's own secrets against it-one silent movement at a time.
The Killer Concerto is a pulse-pounding spy thriller about control, identity, and the cost of reclaiming your voice in a world that profits from your silence. And as this book closes, Celeste realizes she hasn't ended the war-she's only written the first line of the next score.
