Jack Sigler Books in Order

When Manifold Genetics steals an ancient artifact and kidnaps archaeologist George Pierce, Jack Sigler and Chess Team go after them. The chase leads to regenerative soldiers, grotesque experiments, and a mythic predator with far too many heads.

A weaponized genetic disease turns into a silent pandemic, pushing Jack Sigler and Chess Team into Vietnam's remote mountains. They need a cure fast, but the jungle is hiding an ancient threat of its own.

After a devastating attack, Chess Team must protect young Fiona Lane while last speakers of ancient languages are hunted down worldwide. The search leads to living statues, engineered monsters, and a secret that could remake the world.

Pieces of cities begin vanishing in flashes of light, and a scattered Chess Team scrambles to reunite. Their enemy is not merely human, and failure could turn Earth into a feeding ground for an extinction-level predator.

Jack Sigler's parents are kidnapped, his unknown sister appears, and the trail leads to a man calling himself Alexander Diotrephes. The truth is even stranger, because Robinson's Hercules is very much alive and making plans.

Before Chess Team became a legend, Jack Sigler had to build it in the middle of a crisis tied to the Voynich manuscript. Secret science, ancient history, and a biological nightmare make for a brutal origin story.

A stolen tactical nuke, a looming Congo civil war, and a century-old secret pull Chess Team into one of its ugliest missions. The deeper King pushes, the more he realizes not everyone can be saved.

A routine snatch-and-grab against a cartel spirals into a bloodbath when an old enemy resurfaces and a savage outbreak begins spreading. King and Chess Team are suddenly fighting both human killers and something much worse.

Part guidebook, part bonus story, this companion volume gathers Jack Sigler summaries, character files, villain notes, and creature sketches. A new Deep Blue framing tale ties it all back into the series.

A dead sister may be alive, Deep Blue is missing, and the Dyatlov Pass mystery points toward a plan to topple the United States. Chess Team heads into the frozen Russian wilds to stop a new empire from rising.

Chess Team's search for Tom Duncan collides with prehistoric terrors, assassinated presidents, and a space-based weapon. King's latest mission ties global chaos to one final, deadly new kingdom.
