Rome, 145 CE: Cassio, a prominent lawyer who once saved the Emperor's life, wakes in the night to noises. Four assassins have entered his villa and overpowered his formidable slave, the warrior Alva. He seems to know them, and knows why they have come... Ephesus, present day: archeologist Ornella Grazzi finds a ruin with a fresco of Cassio's face. The papyrus scrolls inside tell the beginning of a story she has long suspected and been searching for clues to all her life: how Cassio survived his own assassination and came back from the dead for vengeance...

Having found the first of Cassio's four assassins, archeologist Ornella Grazzi attempts to solve the mystery of the second. And as she pieces together tantalizing fragments of historical evidence, she learns of Cassio's forbidden love for Oasis, virgin priestess of Apis. But why has Cassio traveled to Antioch? Why is he bent on discovering the secrets of its citizens? In the present day, a break-in at the university lab leaves a technician dead and Ornella's findings missing. Could this be the work of the enigmatic Lucas Tanhauser, the older gentleman who has insinuated himself into Ornella's life?

The mystery of Cassio's assassins draws Ornella ever deeper into a world of danger and deception. Her assistant Yani is found murdered. The elderly Maria, housekeeper to the enigmatic Tanhauser, begs her trust, but withholds as much information as she gives. Meanwhile, in the Alexandria of antiquity, Cassio comes the closest yet to getting his revenge on Livion, but his plan threatens to fall through at the hands of the beautiful and tormented Antinoé, the most famous and influential prostitute in the city. What does she know about her master Marcion's plan to subvert the Roman Empire by means of religion?

Cassio tracks the sinister High Priest to his Temple of the Sands in the middle of the desert, only to find himself bested by the High Priest's disciples, who share Cassio's powers but are better trained to control them. It's up to his slave Alva to save him from near death, with help from a mysterious stranger who turns out to be... Cassio's mother! Reveals and reversals abound as, in the present day, Ornella Grazzi finds the fourth murderer, and the origin of Cassio's powers is brought to light in this thrilling conclusion to the first arc of the historical adventure series.

Archeologist Ornella Grazzi may have discovered the identities of Cassio's four murderers, but as intrigue and deception thicken around her, she's realizing just how much she has yet to learn about the life and mysterious powers of the Ancient Roman physician and lawyer. But with her double-crossing assistant shot dead, and now a handsome police detective as well, who can she trust? She'll need to find someone to turn to, and fast, as she dives deeper into Cassio's world to find out why his lover Antinoë betrayed him, and discover the full potential of the strange powders he stole from Egypt...

Cassio may have the ear and favor of Emperor Antoninus, but it's made him more enemies than friends: his aunt's former lover, the Praetorian guardsman Erytheos; the powerful Senator Lernus, father of Cassio's childhood enemy Livion; and even Cassio's faithful former slave Alva. Once she's freed, she joins a plot to take down the very emperor Cassio is trying to save. But Cassio isn't all alone. He's reunited with an old flame, the Apis priestess Oasis. With their rekindled passions, Cassio's magic powders, and the ability of Oasis to see the future, will they triumph over Rome's many traps and betrayals?

Archeologist Ornella Grazzi doesn't know what to expect when she finally meets with the mysterious man who's summoned her to Paris. Billionaire Jon Vegham seems to be playing a complicated game of cat and mouse with her as he doles out clues not only about Ornella's mother and her death from cancer, but also about Cassio, the potentially immortal Roman whom mother and daughter alike were researching. Meanwhile, in ancient Rome, new information about Cassio's own mother, the goddess Armahl, brings him into conflict with his lover, the beautiful priestess Oasis, and his nemesis, the vengeful Egyptian priest Reptah.

A string of beautiful women gruesomely murdered. A cardinal slowly dying from poison in the Vatican. Deranged painter Vali Tesio leaves a trail of brutality across Europe in his quest to draw Jon Vegham from hiding. But just as archeologist Ornella Grazzi finds a mysterious resemblance between the reclusive billionaire who's just hired her and the age-old mummy she's been studying, she receives a call from Maria, the kindly nun who once saved her life: Jon Vegham is not to be trusted! The roots of these feuds and enigmas go back to ancient Rome, and Cassio's struggle against his lifelong enemies.

In this riveting series finale, Tesio, the prophesied child of two ancient Egyptian deities, has recovered his mother's body from the Louvre and wrested the fourth canopic jar from the convent at Monsarmat, leaving a bloody trail of corpses in his wake. Only one man stands any chance of stopping his mad rise to power: his half-brother Cassio. But since Tesio's poison has stripped him of his immortality, Cassio's going to need a lot of help. From the beautiful young archeologist Ornella Grazzi; from his recently resurrected mother, the goddess Armahl; and from the unlikeliest of sources: his mortal enemy, the monstrous Reptah.
