A hidden fire
(Book)

"No secret stays hidden forever." A phone call from an old friend sets Dr. Giovanni Vecchio back on the path of a mystery he'd abandoned years before. He never expected a young librarian could hold the key to the search, nor could he have expected the danger she would attract. Now he and Beatrice De Novo will follow a twisted maze that leads from the archives of a university library, through the fires of Renaissance Florence, and toward a confrontation they never could have predicted.
