The Third of Three Volumes Collecting the Complete Best-Selling Series That Rocketed David Drake to Military Science Fiction Stardom.             This Omni-Trade paperback volume collects the two full-length novels, The Sharp End and Paying the Piper, plus "The Darkness," a novelette which has not appeared in previous Slammers books.             The Hammers are very flawed and imperfect human beings--but they know their jobs, and they get those jobs done, one way or another. If your nation or your planet is under attack, and you want plaster saints to save the day . . . well, lots of luck, and it's been nice knowing  you. But if you really want your chestnuts pulled out of the fire, hire Colonel Hammer's troops. They'll never win a beauty contest, or even a consolation price for "most congenial," but they'll win the war--because they're the best. They're Hammer's Slammers.             This is the third of a three volume set presenting for the first time the entire genre-defining Slammers series in uniform Omni-trade paperback volumes, with new introductions by major SF figures and new afterwords by David Drake. Each volume will also include a Slammers story not collected in previous Slammer's books.                "Fans of Drake's edgy stories of a mercenary tank regiment in a future not all that different from our present will rejoice [at the publication of] the entire series in three volumes. Drake, a Vietnam vet who served in the Blackhorse Regiment, uses prose as cold and hard as the metal alloy of a tank to portray the men and women of Hammer's Regiment. . . .  In his depiction of combat, Drake rivals Crane and Remarque." --Publishers Weekly, reviewing the Night Shade hardcover edition
