Cerberus Group Books in Order

The Cerberus Group books spin out of the Jack Sigler world but develop their own identity quickly. Where Chess Team leans military, Cerberus leans scholarly, mythic, and exploratory, though it still knows how to blow the doors off a scene when needed.

George Pierce is a big part of that shift.

Readers of the Sigler books already know Pierce as the archaeologist who keeps ending up near the wrong artifact at the wrong time. In this series he helps front a very different kind of team, one built to protect dangerous relics, ancient knowledge, and old powers that should not fall into the hands of governments, cults, or opportunists. The idea reaches back to Hercules, who in Robinson's world is not just a legend but part of a much longer hidden history.

That setup lets the books roam across myths and civilizations while keeping a modern-thriller engine underneath. Herculean establishes the group and its purpose. Helios expands the scale with global disasters, historical echoes, and the sense that the world is wobbling toward something much worse. The stakes are still huge, but the energy is different from Chess Team. More secret order than special ops. More relic vault than war room.

The group structure also opens the door to a broader cast. Scientists, historians, fighters, and specialists all have something useful to do, which makes the series feel a little like an adventure puzzle wrapped around an action thriller. Robinson clearly enjoys building that kind of team dynamic.

If you like ancient-mystery thrillers with modern velocity, Cerberus Group is worth your time. It lives close enough to the Sigler books to feel familiar, but it has its own voice, one part myth chase, one part end-of-the-world cleanup crew.
