    Vaughn Killian must hide his past as a ruthless rebel fighter at the risk of imprisonment.  The Carthenogens, "saviors" from another planet, assumed total control of Earth by preaching peace. Eighteen-year-old Vaughn Killian, son of the US ambassador to Thailand, knows otherwise; they killed his parents, forcing him to survive as a rebel for two hellish years in a purge of Bangkok.Now millions are dead and thousands are disappearing in massive airlifts every day, and Killian saw it all. The almond-eyed tyrants have a stranglehold on that information, all militaries, and the world at large.Killian is determined to "resist to the death" and seizes the opportunity to join Black Saber, an elite cadre formed to oppose Carthenogen tyranny. To qualify, he and eleven other candidates must undergo a trial mission on Planet Veritas, a rugged mining outpost where the atmosphere makes people reveal their true selves. Killian must keep his past a secret at the risk of imprisonment. It's a hard thing to do with a body full of scars--especially when Stiles Kerrington, an entitled son of a former US vice president, has singled him out for disqualification. If he fails the mission and can't continue the fight, he'll be jailed while the docile population on Earth is consumed, one city at a time.

    In a Kabbalistic tale of transformation, the executor of an old friend’s will is almost duped into housing his soul. In a tale of time travel between 2015 and 1975, a tragedy sparked by an angel falling onto a pizza shop is reenacted—and the event is barely, but fatally, altered. The cornerstone of the collection is a postscript to the harrowing novel of the haunting of the Romantic poets, The Stress of Her Regard. Once Byron and Shelley break free of the succubus that claimed them, their associate, Trelawny, forges an alliance with Greek rebels to reestablish the deadly connection between man and the nephilim. Fans of Powers’s renowned secret histories will delight as he deftly weaves an array of fantastical creatures into richly layered narratives of the past.

    The Haber-Bosch process, which he invented at the turn of the twentieth century, revolutionized agriculture by converting nitrogen to fertilizer in quantities massive enough to feed the world. The invention has become an essential pillar for life on earth; some two billion people on our planet could not survive without it. Yet this same process supplied the German military with explosives during World War I, and Haber orchestrated Germany's use of an entirely new weapon -- poison gas. Eventually, Haber's efforts led to Zyklon B, the gas later used to kill millions -- including Haber's own relatives -- in Nazi concentration camps.Haber is the patron saint of guns and butter, a scientist whose discoveries transformed the way we produce food and fight wars. His legacy is filled with contradictions, as was his personality. For some, he was a benefactor of humanity and devoted friend. For others, he was a war criminal, possessed by raw ambition. An intellectual gunslinger, enamored of technical progress and driven by patriotic devotion to Germany, he was instrumental in the scientific work that inadvertently supported the Nazi cause; a Jew and a German patriot, he was at once an enabler of the Nazi regime and its victim.Master Mind is a thought-provoking biography of this controversial scientist, a modern Faust who personifies the paradox of science, its ability to create and to destroy. It offers a complete chronicle of his tumultuous and ultimately tragic life, from his childhood and rise to prominence in the heady days of the German Empire to his disgrace and exile at the hands of the Nazis; from early decades as the hero who eliminated the threat of starvation to his lingering legacy as a villain whose work led to the demise of millions.
