The Florentine Meridian Secret

Some secrets are buried in history for a reason. When Florentine manuscript restorer Alessandra Rossi is asked to examine a mysterious Renaissance codex discovered in a forgotten archive, she expects a routine restoration job. Instead, she uncovers a puzzle that was never meant to be solved. Hidden within the fragile pages are encrypted astronomical calculations-far too advanced for the era in which they were written.
The symbols point to a concealed reliquary and a secret left behind by some of the most brilliant minds of the Renaissance. What begins as a historical curiosity quickly becomes something far more dangerous. With the help of historian Julian Mercer and investigator Inspector Conti, Alessandra follows a trail of clues across Europe, from ancient libraries to hidden underground chambers buried beneath historic cities.
But they are not the only ones searching. A brilliant and ruthless collector of forbidden knowledge believes the Codex hides something even greater-and he is willing to do anything to find it first. As the mystery unfolds, Alessandra and her allies discover that the Codex does not simply reveal a forgotten chapter of history. It reveals a warning. A warning written five centuries ago by scholars who believed humanity would one day face a threat from the stars.
Now the race has begun to uncover the truth before it falls into the wrong hands. Because some discoveries can change the future of the world. And some secrets were never meant to be found.
