When cultural anthropologist Dr. Hannah Goldstein loses her husband, Ethan, in a mysterious disappearance, grief is only the beginning. A trail of encrypted messages, hidden artefacts, and Ottoman ruins pulls her into a labyrinth of memory, myth, and AI secrets across Istanbul and beyond.
Ethan wasn't just a financial analyst. He was part of Cedrela-a covert group preserving knowledge too dangerous to name. As Hannah follows a breadcrumb trail through ancient vaults, forgotten musicians, and fractured loyalties, the line between past and present begins to blur.
But she's not the only one searching.
Racing through snow-laced ruins, shadowed alleys, and the buried heart of the city, Hannah must decide: decode Ethan's final message or disappear into the silence he left behind.
Because some conversations never end.
They simply echo louder-until someone listens.
