Sigma Force is a techno-thriller series chronicling the exploits of a covert special forces agency, recruited by the Defense Advanced Research Projects Agency (DARPA) for their incredible intelligence as well as fighting skills. Together the team goes on missions to investigate and secure discoveries, both technological and historical, that threaten the United States and the world.

From the first Rollins adventure set, two miles under Antarctica (Subterranean) to the chilling story of a New Orleans veterinarian caught up in exotic animal smuggling ring (Altar of Eden), experience the true breadth of an author’s creativity and ingenuity.

Spun off from the Sigma universe, a new dynamic duo sets off on their own exploits. Join Tucker Wayne, a former Army Ranger, and his stalwart, four-legged partner, Kane, a military war dog of uncommon valor and intelligence, as they travel the country and the world getting into way too much trouble.

In his first-ever collaboration, James Rollins combines his skill for cutting-edge science and historical mystery with award-winning novelist Rebecca Cantrell's talent for haunting suspense and sensual atmosphere to create a gothic trilogy about an ancient order in the Catholic Church and the hunt for a miraculous book known only as "The Blood Gospel."

In his first middle-school series, James Rollins introduces Jake Ransom, who, along with the boy’s sister, are orphaned when their parents, both archaeologists, disappear during a dig in Mexico. The story starts three years later when a parcel-wrapped package arrives in the mail—no return address, no sign where it came from—inside are the logbooks from their missing parents. This leads to a search across time and mysterious lands to discover the true fate of their parents.

Rollins introduces a fantasy epic like no other. MoonFall opens a riven world trapped between fire and ice, merging his fascination with the natural world, his love of adventure, and his knowledge of the wonders found at the evolutionary fringes of scientific exploration. It centers on a young girl who foretells of a new apocalypse, one that will end all life for all time. It will be up to her and her allies to embark on a journey that will take them into lands, both burning bright and eternally frozen, to face creatures unimaginable and enemies beyond reason—all to save a world that doesn’t want to be saved.

Sample the breadth of James Rollins’s wild imagination and adventurous spirit in this collection of short masterworks, which offer broader insight into his Sigma Force universe while also opening vistas into new landscapes and characters.
