A resurrected star navy hero attempts to keep a fragile interstellar alliance together while battling an implacable alien adversary.Steve White, Vietnam vet, long-time David Weber collaborator and co-author, with Weber, of the New York Times best-seller The Shiva Option, joins with Analog contributor and military SF scholar Charles E. Gannon to carve another notch in the Starfire adventure saga.An implacable foe with telepathic cohesion in battle, near-immortality, and eons-advanced engineering skills threatens to wipe humanity from the galaxy. What's more, they've overcome their one weakness-no faster-than-light travel-and have followed humanity through our star gates and beyond. But humans are the master of adaption, and have got a counterpunch of devastating proportions in reserve. Now a hard-bitten and brilliant admiral must face down renewed alien attack and somehow communicate to the enemy that if he is forced to use his ultimate military option, galactic civilization itself may come to a fiery end.About Extremis:"Vivid. . .Battle sequences mingle with thought-provoking exegesis . . ."-Publishers WeeklyAbout Steve White and David Weber's The Shiva Option:"[Leaves] the reader both exhilarated and enriched." -Publishers WeeklyAbout Steve White:"White offers fast action and historically informed world-building."-Publishers WeeklyAbout Steve White's Forge of the Titans:". . . recalls the best of the John Campbell era of SF.
