“Heart-stopping and relentlessly gripping. Tabor takes us on an odyssey into unfathomable worlds beneath us, and into the hearts of rare explorers who will do anything to get there first.”—Robert Kurson, author of ShadowDivers In 2004, two great scientist-explorers attempted to find the bottom of the world. American Bill Stone took on the vast, deadly Cheve Cave in southern Mexico. Ukrainian Alexander Klimchouk targeted Krubera, a freezing nightmare of a supercave in the war-torn former Soviet republic of Georgia. Both men spent months almost two vertical miles deep, contending with thousand-foot drops, raging whitewater rivers, monstrous waterfalls, mile-long belly crawls, and the psychological horrors produced by weeks in absolute darkness, beyond all hope of rescue. Based on his unprecedented access to logs and journals as well as hours of personal interviews, James Tabor has crafted a thrilling exploration of man’s timeless urge to discover—and of two extraordinary men whose pursuit of greatness led them to the heights of triumph and the depths of tragedy. Blind Descent is an unforgettable addition to the classic literature of true-life adventure, and a testament to human survival and endurance. “Holds the reader to his seat, containing dangers aplenty with deadly falls, killer microbes, sudden burial, asphyxiation, claustrophobia, anxiety, and hallucinations far underneath the ground in a lightless world. Using a pulse-pounding narrative, this is tense real-life adventure pitting two master cavers mirroring the cold war with very uncommonly high stakes.”—Publishers Weekly (starred review) “A fascinating and informative introduction to the sport of cave diving, as well as a dramatic portrayal of a significant man-vs.-nature conflict. . . . What counts is Tabor’s knack for maximizing dramatic potential, while also managing to be informative and attentive to the major personalities associated with the most important cave explorations of the last two decades.”—Kirkus Reviews Includes a 16-pg black and white insert

An updated edition of the blockbuster bestselling leadership book that took America and the world by storm, two U.S. Navy SEAL officers who led the most highly decorated special operations unit of the Iraq War demonstrate how to apply powerful leadership principles from the battlefield to business and life. Sent to the most violent battlefield in Iraq, Jocko Willink and Leif Babin’s SEAL task unit faced a seemingly impossible mission: help U.S. forces secure Ramadi, a city deemed “all but lost.” In gripping firsthand accounts of heroism, tragic loss, and hard-won victories in SEAL Team Three’s Task Unit Bruiser, they learned that leadership—at every level—is the most important factor in whether a team succeeds or fails. Willink and Babin returned home from deployment and instituted SEAL leadership training that helped forge the next generation of SEAL leaders. After departing the SEAL Teams, they launched Echelon Front, a company that teaches these same leadership principles to businesses and organizations. From promising startups to Fortune 500 companies, Babin and Willink have helped scores of clients across a broad range of industries build their own high-performance teams and dominate their battlefields. Now, detailing the mind-set and principles that enable SEAL units to accomplish the most difficult missions in combat, Extreme Ownership shows how to apply them to any team, family or organization. Each chapter focuses on a specific topic such as Cover and Move, Decentralized Command, and Leading Up the Chain, explaining what they are, why they are important, and how to implement them in any leadership environment. A compelling narrative with powerful instruction and direct application, Extreme Ownership revolutionizes business management and challenges leaders everywhere to fulfill their ultimate purpose: lead and win.

It is perhaps a reflection of how technologically controlled our world is that readers increasingly look for science fiction that considers the fates of mankind as a result of increasing scientific domination. This anthology brings together the most extreme examples of the new high-tech, far-future science fiction, pushing the limits way beyond normal boundaries. The stories include: "A Perpetual War Fought Within a Cosmic String", "A Weapon That Could Destroy the Universe", "A Machine That Detects Alternate Worlds and Creates a Choice of Christs", "An Immortal Dead Man Sent To The End of the Universe", "Murder in Virtual Reality", "A Spaceship So Large That There is An Entire Planetary System Within It", and "An Analytical Engine At The End of Time", and "Encountering the Untouchable."
