{"product_id":"the-gutenberg-rubric","title":"The Gutenberg Rubric","description":"Did Gutenberg leave a secret? Just months before the famous Bible that bears his name was finished, Johannes Gutenberg was sued by his partner for misappropriating funds to a private enterprise. When Gutenberg refused to share the secret project, the court awarded the entire Bible-printing operation to Johan Fust, leaving Gutenberg with nothing but his secret. Was it an alchemical formula? A new technology? A heretical treatise? Or something far more dangerous? Why would Gutenberg sacrifice everything? Brilliant, eccentric professor Keith Drucker and rare books librarian Madeline Zayne are reluctant heroes in a centuries-old search for Gutenberg's other book. Crossing continents to follow clues from an encoded rubric and stolen manuscript, the couple faces injury, arcane rituals, and biblio-terrorists as they race to find the fabled treasure. But if they find it, will they survive to tell the world?","brand":"Elder Road LLC","offers":[{"title":"Default Title","offer_id":53020639297856,"sku":"9781939275288","price":15.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0982\/8912\/3648\/files\/imageloader_404de33e-2bbb-400d-8c06-103b411daf7c.jpg?v=1786631877","url":"https:\/\/silverstreetbooks.com\/products\/the-gutenberg-rubric","provider":"silverstreetbooks","version":"1.0","type":"link"}
