In the Balance


Harry Turtledove - 1994
    Machines soared through the air, churned through the seas, crawled across the surface, pushing ever forward, carrying death. Earth was engaged in titanic struggle. Germany, Russia, France, China, Japan: the maps were changing day by day. The hostilities spread in ever-widening ripples of destruction: Britain, Italy, Africa...The fate of the world hung in the balance. Then the real enemy came. Out of the dark of night, out of the soft glow of dawn, out of the clear blue sky came an invasion force the likes of which Earth had never known - and worldwar was truly joined. The invaders were inhuman and they were unstoppable. Their technology was far beyond our reach, and their goal was simple. Fleetlord Atvar had arrived to claim Earth for the Empire. Never before had Earth's people been more divided. Never had the need for unity been greater. And grudgingly, inexpertly, humanity took up the challenge. In this epic novel of alternate history, Harry Turtledove takes us around the globe. We roll with German panzers; watch the coast of Britain with the RAF; and welcome alien-liberators to the Warsaw ghetto. In tiny planes we skim the vast Russian steppe, and we push the envelope of technology in secret labs at the University of Chicago. Turtledove's saga covers all the Earth, and beyond, as mankind - in all its folly and glory - faces the ultimate threat; and a turning point in history shows us a past that never was and a future that could yet come to be...

Her chosen world is Callay, and its enormous, decadent capital metropolis of Tanusha, where the concerns of the war are literally and figuratively so many light years away. But the war between the League and the Federation was ideological as much as political, with much of that ideological dispute regarding the very existence of artificial sentience and the rules that govern its creation. Cassandra discovers that even in Tanusha, the powerful entities of this bloody conflict have wound their tentacles. Many in the League and the Federation have cause to want her dead, and Cassandra’s history, inevitably, catches up with her. Cassandra finds herself at the mercy of a society whose values preclude her own right even to exist.

Weapons of Choice


John Birmingham - 2004
    . . . The impossible has spawned the unthinkable. A military experiment in the year 2021 has thrust an American-led multinational armada back to 1942, right into the middle of the U.S. naval task force speeding toward Midway Atoll—and what was to be the most spectacular U.S. triumph of the entire war. Thousands died in the chaos, but the ripples had only begun. For these veterans of Pearl Harbor—led by Admirals Nimitz, Halsey, and Spruance—have never seen a helicopter, or a satellite link, or a nuclear weapon. And they’ve never encountered an African American colonel or a British naval commander who was a woman and half-Pakistani. While they embrace the armada’s awesome firepower, they may find the twenty-first century sailors themselves far from acceptable.Initial jubilation at news the Allies would win the war is quickly doused by the chilling realization that the time travelers themselves—by their very presence—have rendered history null and void. Celebration turns to dread when the possibility arises that other elements of the twenty-first century task force may have also made the trip—and might now be aiding Yamamoto and the Japanese.What happens next is anybody’s guess—and everybody’s nightmare. . . .From the Trade Paperback edition.
