Anubis Nights: The Fourth Jonathan Shade Novel (Unabridged‪)‬

A dead sorcerer in the underworld named Henry Winslow, a contemporary of Aleister Crowley and former member of The Golden Dawn, steals a spell from the Forbidden Texts in order to fulfill the prophecy of the Thrice Born. He divides himself into three aspects and goes back in time to steal the Emerald Tablets of Thoth from the Great Pyramid of Giza. He wants true immortality and to change the course of history.

Jonathan Shade's old friend, Sharon, shows up with the master of time, Chronos, to send Jonathan and his team into the past to find and kill Winslow.

Jonathan and Kelly arrive in Egypt during the reign of King Tutankhamun. As they appear from nothing, they are mistaken for gods, but when Tut is murdered during a chariot race, things get out of control.

At stake is, well, everything. Because if Winslow succeeds, the world as we know it will no longer exist, wiped from the sands of time.
