Within 24 hours of the Japanese invasion of northern New Guinea at Gona in July 1942, the Australian militiamen of 'B' Company, 39th Battalion, spent four weeks fighting a delaying action against a crack Japanese force outnumbered by three to one. By mid-August, the rest of the battalion had arrived, and these men took up a position at Isurava, in the heart of the cloud covered mountains and jungles of the Owen Stanley Range. At Isurava, this small militia force of the 39th Battalion now numbering around 300 men was determined to make a stand against a crack Japanese force of the 144th Regiment and supporting elements, numbering at least 1500. Then on the day the Japanese launched their attack, to the great relief of these militiamen, reinforcements from the 2nd AIF who had fought with great distinction in the Middle East began to arrive in the afternoon having spent days struggling up the track from Port Moresby. Even so, the Australians were still outnumbered, as the Japanese also received reinforcements, and unlike the Japanese, the Australians had no supporting artillery or medium machineguns. The battle for Isurava would be the defining battle of the Kokoda Campaign and has rightfully been described as Australia's Thermopylae. It was here that Australia's first Victoria Cross in the Pacific war was awarded when the Japanese conducted several ferocious attacks against the Australian perimetre. Private Bruce Kingsbury led an Australian counterattack, rushing forward sweeping the Japanese positions with his Bren gun, saving he situation when all seemed lost -- he was killed leading the charge. Another two men were also nominated for the VC during the fighting at Isurava. The outnumbered and poorly equipped Australians managed to hold back the Japanese advance for almost a week; only then did these battle scared and weary men begin a month long fighting withdraw towards Ioribaiwa Ridge just north of Port Morsby. However, their sacrifice provided time for the Australian 25th Brigade to be brought forward -- finally forcing the Japanese to withdrawal just as they glimpsed the lights of Port Morseby.

NEW YORK TIMES BESTSELLER • In this thrilling novel from Danielle Steel, a small community is tested when their children go missing while exploring a dangerous local peak, forcing them to band together during the crisis. Fishtail, Montana, is home to Anne and Pitt Pollock, local royalty, high school sweethearts, and owners of the successful Pollock ranch. The sprawling foothills of the Beartooth Mountains surround the town, overlooking the Pollocks’ property and the nearby ranch belonging to Bill and Pattie Brown. The two couples have known each other since childhood. Their sons Peter Pollock and Matt Brown are also the best of friends. When they and two other local kids meet Juliet Marshall, new to town after her parents’ bitter divorce, the five of them are soon inseparable, spending their summer days swimming, horseback riding, hiking, and fishing. But one August afternoon, their latest adventure takes a dangerous turn—and quickly escalates into a battle for survival—when they find themselves trapped on Granite Peak. Fear reverberates through the town as their parents grow ever more desperate to hear word that their children have been found. They must place their own trials aside amid a massive search-and-rescue operation. As they come to lean on one another for support, a media frenzy ensues, heightening tensions and testing some already fragile relationships. In the aftermath of this one fateful event, devastating secrets are revealed, new love appears on the horizon, and families are forced to reconsider what they once held dear. In The Challenge, Danielle Steel deftly weaves a story that is a portrait of courage and a striking tale of the bonds of love and family.

This book analyzes the changes brought on to economic and business activities in Latin America due to the new scenarios, environments and social dynamics the world is facing as a result of the COVID-19 pandemic, at both micro- and macroeconomic levels. Recent changes to working environments has brought discussions on work-life balance to the forefront, and creating support mechanisms to attract and retain the next generation of workers has become a primary focus for talent managers. At an industry level, there are expectations that once the crisis passes, there will be massive capital inflows toward ESG investments in emerging markets driving the transformation of companies. Consequently, ESG business models will have a cascading effect in the whole supply chain (upstream, midstream and downstream) and will generate greater value for all stakeholders. At the same time, technologies of the fourth industrial revolution, such as Blockchain and Artificial Intelligence, have gradually been adopted by companies leading the charge in ESG business models. The financial sector has taken the lead in these two technologies, but the challenge generated by the COVID-19 pandemic forced other sectors to innovate rapidly in order to remain afloat. Using empirical and theoretical frameworks, the contributors in this book identify the most attractive alternatives to benefit consumers in an adverse environment like the one the world is facing as a result of the COVID-19 pandemic, which while posing a significant challenge for most industries, has also created new opportunities for innovation and ingenuity, analyzing case studies from the coffee and medical tourism sectors in particular.
