History remembers the Soviets and the Nazis as bitter enemies and ideological rivals - the two opposing totalitarian regimes of World War II whose conflict would be the defining and deciding clash of the war. Yet for nearly a third of the conflict's entire timespan, Hitler and Stalin stood side by side as partners.

While the Battle of Kursk has long captivated World War II aficionados, it has been unjustly overlooked by historians. Drawing on the masses of new information made available by the opening of the Russian military archives, Dennis E. Showalter at last corrects that error. This battle was the critical turning point on World War II's Eastern Front. In the aftermath of the Red Army's brutal repulse of the Germans at Stalingrad, the stakes could not have been higher.

Riley Black brings us back in time to prehistoric seas, swamps, forests, and savannas where critical moments in plant evolution unfolded. Each chapter stars plants and animals alike, underscoring how the interactions between species have helped shape the world we call home. As the chapters move upwards in time, Black guides listeners along the burgeoning trunk of the Tree of Life, stopping to appreciate branches of an evolutionary story that links the world we know with one we can only just perceive now through the silent stone, from ancient roots to the present.

By 1943, the war was lost, and most German officers knew it. What kept the German army going in an increasingly hopeless situation? Where some historians have found explanations in the power of Hitler or the role of ideology, Robert M. Citino, the world's leading scholar on the subject, posits a more straightforward solution: Bewegungskrieg, the way of war cultivated by the Germans over the course of history. In this book, Citino charts the path by which Bewegungskrieg, or a "war of movement," inexorably led to Nazi Germany's defeat.

We humans are the inheritors of a dynasty that has reigned over the planet for nearly 66 million years, through fiery cataclysm and ice ages: the mammals. Our lineage includes saber-toothed tigers, woolly mammoths, armadillos the size of a car, cave bears three times the weight of a grizzly, clever scurriers that outlasted Tyrannosaurus rex, and even other types of humans, like Neanderthals.

David Stahel's groundbreaking new account of Operation Typhoon captures the perspectives of both the German high command and individual soldiers, revealing that despite success on the battlefield the wider German war effort was in far greater trouble than is often acknowledged.

In the darkest part of the solar system lies a wormhole. Nether. Astrophysicist Cammie Skoura has joined the first research team traveling to the Nether anomaly, eager to understand the mechanics of the wormhole and to explore its possibilities as a shortcut to Alpha Centauri. But another race of ancient beings has already been here—an impossibly long time ago—leaving remnants of their vast complexes and gigantic temples built for horrific beings beyond comprehension.

The West and Islam - the sword and scimitar - have clashed since the 17th century, when, according to Muslim tradition, the Roman emperor rejected Prophet Muhammad's order to abandon Christianity and convert to Islam, unleashing a centuries-long jihad on Christendom. Sword and Scimitar chronicles the decisive battles that arose from this ages-old Islamic jihad, beginning with the first major Islamic attack on Christian land in 636.
