- Reimagines the Epic of Gilgamesh in the context of Sitchin's discoveries

- Details ancient Sumerian sex rituals, the Anunnaki lineage of the gods who lived in Sumer, Anunnaki spacecraft technology, the workings of the Oracle of Anu, and Gilgamesh's relationship with the goddess Ishtar

Written in secret so as not to incite criticism about his controversial discoveries, this novel from the late Zecharia Sitchin brings to life the key themes of his bestseller The 12th Planet. The story begins in London as Astra arrives at the British Museum's opening for their new Gilgamesh exhibit. There she meets a handsome stranger who knows secrets about her that no stranger should know, including the source of the unusual scar on her hand. Taking her to his apartment, he reveals that she is descended from the goddess Ishtar and that he is the modern-day avatar of Gilgamesh seeking to claim the eternal life Ishtar denied him so long ago. Reenacting their sacred sex ritual from eons ago, they find themselves transported to ancient Sumer as Gilgamesh and Ishtar, where he is at last able to continue his quest for immortality.

But as Gilgamesh fulfills his sacred duties with Ishtar, something goes awry and the Oracle of Anu will not renew its blessing upon his kingship. Following the direction of his mother, the Anunnaki goddess Ninsun--the source of his partial divinity--Gilgamesh flees the city for the Anunnaki forbidden zone in search of a way to the planet Nibiru and eternal life. Travel alongside Gilgamesh and his immortal companion Enkidu as they escape the fate pronounced by the oracle, discover a Tablet of Destiny meant for Ishtar, fight off Marduk's raiders, and foil the plot of the high priest, Gilgamesh's half-brother who is seeking Gilgamesh's crown for himself.

Retelling the Epic of Gilgamesh in the context of his discoveries about the Anunnaki, Zecharia Sitchin weaves a tale of ancient ceremony, accidental betrayal, gods among men, interplanetary travel, and a quest for immortality spanning millennia.
