Cambridge archaeologist Sarah Weston makes an unusual discovery in the ancient Ethiopian mountain kingdom of Aksum: a sealed tomb with inscriptions in an obscure dialect. Seeking to ascertain the translation and the identity of the entombed man, she and her colleague, American anthropologist Daniel Madigan, stumble upon a lethal conflict.
Tracking down clues in Addis Ababa and the monasteries of Lalibela, Sarah and Daniel uncover a codex in a subterranean library revealing a set of prophecies about Earth’s final hours written by a man hailed by Coptic mystics as Ethiopia’s tenth saint. Violently opposed by the corrupt director of antiquities at the Ethiopian Ministry of Culture and Tourism, they’re left for dead in the heart of the Simien Mountains. Surviving to journey to Paris, Sarah is given another piece of the ancient puzzle: a fourteenth-century letter describing catastrophic events leading to the planet’s demise.
Connecting the two discoveries, Sarah faces a deadly intercontinental conspiracy to keep the secret of the tenth saint buried. Risking her reputation and her life, Sarah embarks on a quest to stall the technological advances that will surely destroy the world.
