Book Description
From the author of Nursery Earth, a “nimble, fast, surprising, smart, and weird in the very coolest sense of the word” (Sy Montgomery) exploration of the sometimes enormous, often bizarre creatures that ruled the seas long before the first dinosaurs—a Science Friday Book Club Pick Cephalopods, Earth’s first truly substantial animals, are still among us: Their fascinating family tree features squid, octopuses, nautiluses, and more. The inventors of swimming, cephs presided over the sea for millions of years. But when fish evolved jaws, cephs had to step up their game (or end up on the menu). Some evolved defensive spines. Others abandoned their shells entirely, opening the floodgates for a tidal wave of innovation: masterful camouflage, fin-supplemented jet propulsion, and intelligence we’ve yet to fully measure. In Monarchs of the Sea, marine biologist Danna Staaf unspools how these otherworldly creatures once ruled the deep—and why they still captivate us today. Publisher’s Note: Monarchs of the Sea was previously published in hardcover as Squid Empire.

Book Description
Before there were mammals on land, there were dinosaurs. And before there were fish in the sea, there were cephalopods-the ancestors of modern squid and Earth's first truly substantial animals. Cephalopods became the first creatures to rise from the seafloor, essentially inventing the act of swimming. With dozens of tentacles and formidable shells, they presided over an undersea empire for millions of years. But when fish evolved jaws, the ocean's former top predator became its most delicious snack. Cephalopods had to step up their game. Many species streamlined their shells and added defensive spines, but these enhancements only provided a brief advantage. Some cephalopods then abandoned the shell entirely, which opened the gates to a flood of evolutionary innovations: masterful camouflage, fin-supplemented jet propulsion, perhaps even dolphin-like intelligence. Squid Empire is an epic adventure spanning hundreds of millions of years, from the marine life of the primordial ocean to the calamari on tonight's menu. Anyone who enjoys the undersea world-along with all those obsessed with things prehistoric-will be interested in the sometimes enormous, often bizarre creatures that ruled the seas long before the first dinosaurs.

Book Description
“What a wonderful idea for an adventure! Absolutely inspired, timely, and important.” —Alistair Humphreys, National Geographic Adventurer of the Year and author of The Doorstep Mile and Around the World by Bike Outdoor educator and field researcher Sara Dykman made history when she became the first person to bicycle alongside monarch butterflies on their storied annual migration—a round-trip adventure that included three countries and more than 10,000 miles. Equally remarkable, she did it solo, on a bike cobbled together from used parts. Her panniers were recycled buckets. In Bicycling with Butterflies, Dykman recounts her incredible journey and the dramatic ups and downs of the nearly nine-month odyssey. We’re beside her as she navigates unmapped roads in foreign countries, checks roadside milkweed for monarch eggs, and shares her passion with eager schoolchildren, skeptical bar patrons, and unimpressed border officials. We also meet some of the ardent monarch stewards who supported her efforts, from citizen scientists and researchers to farmers and high-rise city dwellers. With both humor and humility, Dykman offers a compelling story, confirming the urgency of saving the threatened monarch migration—and the other threatened systems of nature that affect the survival of us all.

Book Description
As the politico-economic exploits of vikings in and around the Frankish realm remain, to a considerable extent, obscured by the constraints of a fragmentary and biased corpus of (near-)contemporary evidence, this volume approaches the available interdisciplinary data on a cumulative and conceptual level, allowing overall spatiotemporal patterns of viking activity to be detected and defined – and thereby challenging the notion that these movements were capricious, haphazard, and gratuitous in character. Set against a backdrop of continuous commerce and knowledge exchange, this overarching survey demonstrates the existence of a relatively uniform, sequential framework of wealth extraction, encampment, and political engagement, within which Scandinavian fleets operated as adaptable, ambulant polities – or ‘hydrarchies’. By delineating and visualising this framework, a four-phased conceptual development model of hydrarchic conduct and consequence is established, whose validity is substantiated by its application to a number of distinct regional case studies. The parameters of this abstract model affirm that Scandinavian movements across Francia were the result of prudent and expedient decision-making processes, contingent on exchanged intelligence, cumulative experience, and the ongoing individual and collective need for socioeconomic subsistence and enrichment. Monarchs and Hydrarchs will appeal to both students and specialists of the Viking Age, whilst serving as an equally valuable resource to those investigating early medieval Francia, Scandinavia, and the North Sea world as a whole.

Book Description
In this thrilling conclusion to New York Times bestselling authors Kass Morgan and Danielle Paige’s The Ravens duology, loyalty, love, and friendships are tested as sorority sisters Scarlett and Vivi must face the forces of hell itself when a rival sorority threatens to wreak havoc on campus. The ultra-exclusive Kappa Rho Nu—the Ravens—are determined to restore balance to the world. After destroying an ancient talisman and barely saving their sorority in the process, they’ll go to any lengths to keep their secret as Westerly’s most powerful coven of witches. Scarlett Winter, a legacy Raven, has finally gotten what she’s always wanted: Scarlett is Kappa Rho Nu’s newest president. Unlike her mother or older sister before her, Scarlett has a vision for a more unified Kappa, one where no sister falls to the forces of wicked magic. But the powers of the presidency have their own pitfalls. And with the pressures of alumni bureaucracy and past failures weighing on her, Scarlett finds herself at risk of losing the very thing that defined her: her magic. As a new member of Kappa Rho Nu, Vivi Devereaux finally knows what it’s like to belong. She has her Kappa Rho Nu sisters behind her and, with Scarlett’s blessing, Vivi’s happily dating her first college crush (who also just happens to be Scarlett’s ex). When Scarlett assigns Vivi the coveted role of social chair, Vivi is determined to live up to her Big’s expectations. But Vivi’s studies in witchcraft take a deadly turn when she uncovers a new form of magic, one that has mysterious ties to Kappa Rho Nu’s past and the vengeful demon once tied to their talisman. With the weight of their newfound roles and the terrible price of destroying the talisman haunting them, Scarlett and Vivi must save their sisterhood when the forces of hell itself and a rival sorority threaten to unleash havoc on the Ravens.

Book Description
In 1521, Suleiman the Magnificent, Muslim ruler of the Ottoman Empire at the height of its power, dispatched an invasion fleet to the Christian island of Rhodes. This would prove to be the opening shot in an epic struggle between rival empires and faiths for control of the Mediterranean and the center of the world. In Empires of the Sea, acclaimed historian Roger Crowley has written his most mesmerizing work to date–a thrilling account of this brutal decades-long battle between Christendom and Islam for the soul of Europe, a fast-paced tale of spiraling intensity that ranges from Istanbul to the Gates of Gibraltar and features a cast of extraordinary characters: Barbarossa, “The King of Evil,” the pirate who terrified Europe; the risk-taking Emperor Charles V; the Knights of St. John, the last crusading order after the passing of the Templars; the messianic Pope Pius V; and the brilliant Christian admiral Don Juan of Austria. This struggle’s brutal climax came between 1565 and 1571, seven years that witnessed a fight to the finish decided in a series of bloody set pieces: the epic siege of Malta, in which a tiny band of Christian defenders defied the might of the Ottoman army; the savage battle for Cyprus; and the apocalyptic last-ditch defense of southern Europe at Lepanto–one of the single most shocking days in world history. At the close of this cataclysmic naval encounter, the carnage was so great that the victors could barely sail away “because of the countless corpses floating in the sea.” Lepanto fixed the frontiers of the Mediterranean world that we know today. Roger Crowley conjures up a wild cast of pirates, crusaders, and religious warriors struggling for supremacy and survival in a tale of slavery and galley warfare, desperate bravery and utter brutality, technology and Inca gold. Empires of the Sea is page-turning narrative history at its best–a story of extraordinary color and incident, rich in detail, full of surprises, and backed by a wealth of eyewitness accounts. It provides a crucial context for our own clash of civilizations.
