Disgraced medieval symbologist Silas Reed thought his career had ended when the academic world dismissed his controversial theories about Gothic stained glass. But when his former mentor is brutally murdered, Silas receives a final encrypted message pointing toward an impossible secret hidden within seven ancient cathedral windows across Europe. As he follows a trail of forgotten manuscripts, mysterious symbols, and breathtaking Gothic architecture, he discovers that the windows are far more than masterpieces of medieval art—they are pieces of an advanced optical network capable of revealing a hidden location buried beneath history itself. Hunted by a ruthless organization determined to erase every trace of the truth, Silas must decode each window before the final secret is lost forever. Combining archaeological mystery, historical intrigue, cutting-edge science, and relentless suspense, Seven Windows delivers a gripping conspiracy thriller where every ray of light hides another clue, and every discovery brings death one step closer.
