Facts, fiction and everything between. By AJO, author of The Whisper of the Nuraghi (MAREVA Editions).
No. 19.3 Hz is a fictional device invented for the novel. The science around it is real: infrasound (below ~20 Hz) affects the human body, and acoustic archaeology studies how ancient structures shape sound. The specific frequency and the "singing tower" are fiction — deliberately grown out of real research, including the 2006 anomalous low-frequency signals reported by Latronico and colleagues at Gola su Gorropu.
Roughly 7,000 Bronze Age stone towers built in Sardinia between about 1900 and 700 BCE by a civilization that left no written records. Their purpose is still debated: fortresses, status symbols, and acoustic functions are among the leading hypotheses — the last of which is the seed of this novel.
Yes. Su Nuraxi di Barumini (UNESCO World Heritage Site since 1997), Orgosolo, Gola su Gorropu, Santu Antine, Santa Cristina and Tiscali are all real and visitable. The free Archaeological Map lists 20+ sites from the book.

Each book is a standalone mystery. The Whisper of the Nuraghi (five books planned, part of a wider 30-book MAREVA universe) rewards reading in order, but Book One works on its own.
AJO (阿乔) is a writer who has lived between Sardinia and China for more than a decade, founder of MAREVA Editions — and a recurring thread inside the book universe itself.
