About this book:

**Dive into a labyrinth of ancient secrets and deadly modern conspiracies where a single manuscript holds the key to a forgotten library—and a centuries-old curse that could reshape the world.** Dr. Leila Hassan, a renowned Islamic art historian, uncovers a cryptic code hidden within the gilded margins of a 16th-century Ottoman text, catapulting her into a deadly game of intellectual pursuit and survival. As shadowy figures from the enigmatic Keepers of the Veil close in, she must decode geometric riddles tied to lost cisterns, celestial alignments, and the resting place of Sultan Ahmed I’s mythical Library of the Sultan. Each clue unravels a deeper mystery, from hidden chambers beneath Istanbul’s Hippodrome to alchemical formulas that predate modern science, all while racing against those determined to keep the past buried forever.

**In this pulse-pounding historical thriller, the line between myth and reality blurs as Dr. Hassan navigates a web of betrayal, ancient oaths, and the haunting echoes of a curse that binds the past to the present.** From the hallowed halls of Oxford to the atmospheric ruins of Constantinople, every page crackles with tension, as the scholar’s quest becomes a fight not just for knowledge—but for her life. Will she unlock the Sultan’s legacy before it unlocks its own deadly reckoning? The truth awaits in the shadows, and time is running out.
