Ramses the Damned (Christopher Rice) Books in Order

Ramses the Damned is a shared world between Anne Rice and Christopher Rice, built on her earlier novel The Mummy, or Ramses the Damned and continued in the co written books Ramses the Damned: The Passion of Cleopatra and Ramses the Damned: The Reign of Osiris.(en.wikipedia.org)

The series imagines that Ramses the Great was granted immortality by a potent Elixir of Life. Centuries later his sarcophagus is unearthed by archaeologist Lawrence Stratford, and Ramses wakes in Edwardian England with the strength and appetites of an undying man who has seen empires rise and fall. He soon forms a bond with Stratford's daughter Julie, even as his very existence threatens to upend the polite world she inhabits.(en.wikipedia.org)

In The Passion of Cleopatra Ramses' hunger for connection leads him to a rash act. Certain that he can restore his ancient lover, he uses the Elixir to resurrect Cleopatra herself. The queen returns with fractured memories and a dangerous charisma, and the story widens to include Sybil Parker, an American novelist whose vivid dreams of ancient Egypt may be something more than imagination. Old grudges and new obsessions play out across London drawing rooms, Egyptian ruins, and the spiritual landscape that binds Ramses and Cleopatra together.(en.wikipedia.org)

The Reign of Osiris pushes the mythology further. With the specter of world war looming, Ramses, Julie, Cleopatra, and the immortal queen Bektaten confront Russian assassins who wield mysterious jewels capable of animating statues and turning ritual into living weapons. The search for the origins of that power sends the immortals from Mediterranean shores to the forests of Russia, and forces Ramses to face how far the Elixir's influence has spread.(penguinrandomhouse.com)

Across the books, the tone drifts between historical horror, adventure, and sweeping romance. Questions of immortality are treated as both gift and burden. Ramses and Cleopatra can cross oceans and centuries, but they cannot easily escape grief, jealousy, or responsibility for the people who drink the same Elixir. Christopher Rice's hand is especially visible in the expanded origin story of the potion and in the tighter, thriller like pacing of the later installments.(en.wikipedia.org)

If you are reading for Christopher Rice in particular, the Ramses novels show how his interest in damaged heroes, ethical gray areas, and supernatural world building adapts to a setting of ocean liners, archaeological digs, and candlelit palaces. The stakes are enormous, but the series always circles back to individual choices, the cost of loving someone who might live forever, and what it means to hold power that can literally cheat death.
