THE SECRET MUST BE KEPT… For three thousand years, the Herculean Society has preserved the legacy of the ancient hero, Hercules, protecting history’s fragile relics from humanity, and humanity from the dangerous truths behind the legends. Now, the Society’s new leader, archaeologist George Pierce, faces his first test: the Cerberus Group. The shadowy organization has two goals: the collection and distribution of black market relics, tech and secrets, and the purge of those deemed unfit for survival. Pierce and his niece, Fiona—the last guardian of the ‘mother tongue,’ the forgotten language of creation—discover a secret entrance to the legendary Labyrinth, and at its heart, a hidden trove of relics that point the way to Hercules’s greatest discovery: a mutagen that can rewrite the very code of life. When a surprise attack leaves Pierce and Fiona trapped in the deadly maze, fighting for their lives, the race to stop the Cerberus Group begins. To defeat this new enemy, Pierce must assemble a team of experts including Felice Carter, a geneticist with a dangerous secret, Augustina Gallo, a mythology professor, Cintia Dourado, a high tech hacker, and Lazarus, a dead soldier returned to life. Guided by their knowledge of science, history and mythology, Pierce’s team sets out on an epic journey, following in the footsteps of Hercules, to stop Cerberus from controlling the power that rises from the Well of Monsters. …OR THE WORLD WILL BE CLEANSED. Jeremy Robinson and Sean Ellis, the international bestselling team behind the Jack Sigler thrillers, including Savage and Cannibal, return with new series that rewrites the way we see history. Rivaling the best of Matthew Reilly and James Rollins, Herculean combines a blistering pace with fringe science and myths reborn.

A deadly swarm of earthquakes shakes the planet. In the sky above, the sun appears to stand still. While the world reels from the vast destruction, George Pierce and the Cerberus Group, a team of scientific and historical experts, uncover an imminent threat straight out of history that must be stopped. But not everyone wants them to succeed. An apocalyptic death cult, made up of suicidal martyrs and true believers who will do whatever it takes to ensure the destruction of all life on Earth, goes head-to-head with a billionaire tech-genius commanding an army of robots, on a quest to own the sun itself. Caught in the middle, the Cerberus Group must fend off both sides while traveling to every corner of the map, and into the depths of myth and history, to find the holiest treasure on Earth—an artifact that can harness the power of creation. The prophecies are true. THE END IS NIGH. Jeremy Robinson and Sean Ellis, the international bestselling team behind the Jack Sigler thrillers, including Cannibal and Empire, continue the new series that rewrites the way we see history. Rivaling the best of Matthew Reilly and James Rollins, Helios combines a blistering pace with fringe science and myths reborn.
