Book
Old Man's War
by John Scalzi
John Perry did two things on his 75th birthday. First he visited his wife’s grave. Then he joined the army. The good news is that humanity finally made it into interstellar space. The bad news is that planets fit to live on are scarce—and alien races willing to fight us for them are common. So: we fight. To defend Earth, and to stake our own claim to planetary real estate. Far from Earth, the war has been going on for decades: brutal, bloody, unyielding. Earth itself is a backwater. The bulk of humanity’s resources are in the hands of the Colonial Defense Force. Everybody knows that when you reach retirement age, you can join the CDF. They don’t want young people; they want people who carry the knowledge and skills of decades of living. You’ll be taken off Earth and never allowed to return. You’ll serve two years at the front. And if you survive, you’ll be given a generous homestead stake of your own, on one of our hard-won colony planets. John Perry is taking that deal. He has only the vaguest idea what to expect. Because the actual fight, light-years from home, is far, far harder than he can imagine—and what he will become is far stranger. "Solid . . . [Scalzi] sidesteps most of the clichés of military science fiction, delivers fast-paced scenes of combat and pays attention to the science underpinning his premise." —San Francisco Chronicle "Scalzi's imagined interstellar arena is coherently and compellingly delineated . . . His speculative elements are top-notch. His combat scenes are blood-roiling. His dialogue is suitably snappy and profane. And the moral and philosophical issues he raises . . . insert useful ethical burrs under the military saddle of the story." —Paul Di Filippo, The Washington Post "Thought-provoking!" —Entertainment Weekly "Smartly conceived and thoroughly entertaining, Old Man’s War is a splendid novel." –Cleveland Plain Dealer "When humanity reaches the stars, it discovers that it must defend its claim to new planets against alien races with similar expansionist tendencies. To ensure the expertise of its soldiers, Earth creates the Colonial Defense Force, an army of men and women otherwise classified as senior citizens, who give up their lives on Earth for an uncertain and perilous future among the stars. Scalzi's first novel presents a new approach to military sf, boasting an unusual cast of senior citizens as heroes. A good choice for most libraries." —Library Journal "Though a lot of SF writers are more or less efficiently continuing the tradition of Robert A. Heinlein, Scalzi’s astonishingly proficient first novel reads like an original work by the late grand master . . . This virtuoso debut pays tribute to SF’s past while showing that well-worn tropes still can have real zip when they’re approached with ingenuity." —Publishers Weekly (starred review) "Gripping and surpassingly original. It's Starship Troopers without the lectures. It's The Forever War with better sex. It's funny, it's sad, and it's true." —Cory Doctorow "John Scalzi is a fresh and appealing new voice, and Old Man's War is classic SF seen from a modern perspective—a fast-paced tour of a daunting, hostile universe." —Robert Charles Wilson "I enjoyed Old Man's War immensely. A space war story with fast action, vivid characters, moral complexity and cool speculative physics, set in a future you almost want to live into, and a universe you sincerely hope you don't live in already." —Ken MacLeod

Book
The Ghost Brigades
by John Scalzi
The Ghost Brigades are the Special Forces of the Colonial Defense Forces, elite troops created from the DNA of the dead and turned into the perfect soldiers for the CDF's toughest operations. They’re young, they’re fast and strong, and they’re totally without normal human qualms. The universe is a dangerous place for humanity—and it's about to become far more dangerous. Three races that humans have clashed with before have allied to halt our expansion into space. Their linchpin: the turncoat military scientist Charles Boutin, who knows the CDF’s biggest military secrets. To prevail, the CDF must find out why Boutin did what he did. Jared Dirac is the only human who can provide answers -- a superhuman hybrid, created from Boutin's DNA, Jared’s brain should be able to access Boutin's electronic memories. But when the memory transplant appears to fail, Jared is given to the Ghost Brigades. At first, Jared is a perfect soldier, but as Boutin’s memories slowly surface, Jared begins to intuit the reason’s for Boutin’s betrayal. As Jared desperately hunts for his "father," he must also come to grips with his own choices. Time is running out: The alliance is preparing its offensive, and some of them plan worse things than humanity’s mere military defeat... "A mix of Starship Troopers and Universal Soldier, Ghost Brigades evokes awakening, betrayal, and combat in the best military sci-fi tradition."—Entertainment Weekly "An impressive piece of work."—Philadelphia Inquirer "Fast and deep . . . I like the galaxy this author's playing in, the characters he limns, the situations he's playing with, and I'm glad there's at least one more volume on the way."—San Diego Union-Tribune "In Heinleinesque fashion, the book is loaded with scenes of comradeship, isolation, ruthlessness and the protocols, which govern the lives of active-duty soldiers. But this is where Scalzi, famous for his blog ‘The Whatever,’ surpasses Heinlein. Scalzi weaves in subtle discussions of humanity's growing fear of aging and our simultaneous attraction and repulsion to the Frankenstein-like creatures we are able to create."—San Antonio Express-News "Scalzi is a natural heir to Heinlein, and his second book in this series is a good old-fashioned space opera, which takes time to question the nature of free will."—St. Louis Press-Dispatch "The alliance of three alien races against interstellar humanity, the defection of a human military scientist, and the signs of an impending war call for desperate measures from the Colonial Defense Forces. The creation of the superhuman hybrid Jared Dirac from the DNA of the traitor Charles Boutin is intended to provide a window on Boutin's mind and on the reasons for the alien alliance, but the transfer apparently fails, and Dirac is assigned to the Ghost Brigades, Special Forces troops cloned from the DNA of dead men minus any moral qualms. The sequel to Old Man's War combines taut military action with keen insights into the moral issues revolving around developing technologies. Scalzi has a finely tuned sense of balance between personal drama and the ‘big picture’ in this SCI FI Essential Book choice. Highly recommended."—Library Journal (starred review) "Scalzi's riveting and original Old Man's War introduced readers to the Colonial Defense Forces (CDF), an Earth-based galactic army composed of senior citizens rejuvenated by high-tech wizardry into youthful warriors. In this equally engaging, battle-driven sequel, the CDF's latest operation entails tracking down renegade scientist Charles Boutin, who is responsible for handing over deadly military secrets to humanity's extraterrestrial enemies. Fortunately, a computer-based replica of Boutin's consciousness is on file and ready for transfer into newly cloned special-forces soldier Jirad Dirac, who shares Boutin's DNA. When the consciousness transfer doesn't quite take, Dirac is handed off to a battalion for routine but closely monitored training. Just when Dirac is getting comfortable with his own identity, however, Boutin's memories kick in, and Dirac and his team are summarily dispatched to an enemy planet to capture Boutin and solve the mystery of his treason before humanity is destroyed. Scalzi skillfully weaves together action, memorable characterizations, and a touch of philosophy in a first-rate military sf outing."—Carl Hays, Booklist "[A] fast-paced interstellar military drama . . . It follows Jared Dirac, a superhuman soldier, from unusual birth to ambiguous death. Dirac is an altered clone of Charles Boutin, a military scientist who betrayed humankind to alien aggressors, and the Colonial Defense Forces' only hope of finding Boutin lies in transplanting his memories into Dirac's brain. When the transplant seems to fail, Dirac is sent to Special Forces, known as the Ghost Brigades for their habit of creating new soldiers from the DNA of the dead. His indoctrination there comes in handy when Boutin's memories begin to surface. Scalzi pays gleeful homage to Ender's Game, The Forever War and Starship Troopers."—Publishers Weekly
