An artifact found by their parents—on the expedition from which they never returned—leads Jake and Kady to a strange world inhabited by a peculiar mix of long-lost civilizations, a world that may hold the key to their parents' disappearance. But even as they enter the gate to this extraordinary place, savage grackyls soar across the sky, diving to attack. Jake's new friends, the pretty Mayan girl Marika and the Roman Pindor, say the grackyls were created by an evil alchemist—the Skull King. And as Jake struggles to find a way home, it becomes obvious that what the Skull King wants most is Jake and Kady—dead or alive.

Bestselling novelist James Rollins brings to life the adventures of Jake Ransom, who became an orphan when his archaeologist parents disappeared on a dig three years ago. They left behind tokens—half of an ancient coin for Jake, and the other half for his sister Kady—that fit perfectly into one of their famous discoveries. When everything falls into place, Jake and Kady find themselves in the mysterious, bizarre world of Pangea—home of vicious raptors, bloodthirsty plants, and dark Mayan and Egyptian rituals. And whatever caught their parents is still hungry. The books described as "Indiana Jones for tweens" are perfect for fans of Alex Rider, Percy Jackson, and National Treasure. Includes Jake Ransom and the Skull King's Shadow and Jake Ransom and the Howling Sphinx.

Four millennia have passed since the gods came to Myrillia, creating the nine lands of peace as a haven from the nightmarish, accursed Hinterlands. In all this time nothing has disturbed the harmony of the nine lands. But now the goddess of the Summering Isles has been murdered. The only witness is Tylar de Noche, a crippled and disgraced former Shadowknight. As he holds the dying goddess, her last breath bestows a powerful blessing on him-a mark that heals his broken body. A mark that many see as proof that he killed a god. A mark that unleashes a powerful force of darkness within him. Chased across Myrillia by enemies both human and ethereal, Tylar must uncover and face down a being powerful enough to kill an immortal-the true godslayer. For if he fails, all of Myrillia will fall into shadow.

In The Eye of God, a Sigma Force novel, New York Times bestselling author James Rollins delivers an apocalyptic vision of a future predicted by the distant past. In the wilds of Mongolia, a research satellite has crashed, triggering an explosive search for its valuable cargo: a code-black physics project connected to the study of dark energy—and a shocking image of the eastern seaboard of the United States in utter ruin. At the Vatican, a package arrives containing two strange artifacts: a skull scrawled with ancient Aramaic and a tome bound in human skin. DNA evidence reveals that both came from the same body: the long dead Mongol king Genghis Khan. Commander Gray Pierce and Sigma Force set out to discover a truth tied to the fall of the Roman Empire, to a mystery going back to the birth of Christianity, and to a weapon hidden for centuries that holds the fate of humanity.

From James Rollins, the #1 New York Times bestselling author of the Sigma Force series, comes another electrifying combination of suspense, history, science, action, and ingenious speculation. Deep in the Rocky Mountains, a gruesome discovery—hundreds of mummified bodies—stir international attention and fervent controversy. Despite doubts about the bodies’ origins, the local Native American Heritage Commission lays claim to the prehistoric remains, along with the strange artifacts found in the same cavern: gold plates inscribed with an unfathomable script. During a riot at the dig site, an anthropologist dies horribly: burned to ash in a fiery explosion in plain view of television cameras. All evidence points to a radical group of Native Americans, including one agitator, a teenage firebrand who escapes with a vital clue to the murder and calls on the one person who might help: her uncle, Painter Crowe, director of Sigma Force. To protect his niece and uncover the truth, Painter will ignite a war across the nation’s most powerful intelligence agencies. Yet, an even greater threat looms as events in the Rocky Mountains have set in motion a frightening chain reaction, a geological meltdown that threatens the entire western half of the U.S. From the volcanic peaks of Iceland to the blistering deserts of the American Southwest, from the gold vaults of Fort Knox to the bubbling geysers of Yellowstone, Painter Crowe joins forces with Commander Gray Pierce to penetrate the shadowy heart of a dark cabal, one that has been manipulating American history since the founding of the thirteen colonies. But can he discover the truth—one that could topple governments—before it destroys all he holds dear?
