{"product_id":"guy-roberts-the-open-door-cadenza-9798231262212","title":"The Open-Door Cadenza","description":"When Vienna breaks him, conductor Kaspar Linhardt swears off the podium-until he meets Mina Corvin, a sound researcher proving that music can retune the body without stealing the soul. Together they design underground concerts that heal: fifths for steadiness, seconds for shared memory, and runic \"seatbelts\" that make consent part of the score.Then a powerful patron demands a command performance to \"purge\" a political crowd.To stop the weaponization of wonder, Kaspar and Mina rewrite the music itself-cadences that only close when the audience breathes yes, lights that listen for refusal, and stages that won't turn a room into a machine. When sabotage strikes a premiere, they lead those who choose to follow into a hidden crypt-temple and finish the symphony where stones remember how to tell the truth.Symphony of Four is a music-core romantasy with moral stakes-a story about rooms that heal, the courage to refuse the baton, and the braver harmony that happens when people carry the ending themselves.","brand":"guy roberts","offers":[{"title":"Default Title","offer_id":53732899881302,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":false}],"url":"https:\/\/www.momoxbooks.com\/products\/guy-roberts-the-open-door-cadenza-9798231262212","provider":"momoxbooks","version":"1.0","type":"link"}
