Sixteen-year-old Iduna harbors a dark secret. On the surface, she is an Arendellian village girl, an aspiring inventor, and the best friend of Prince Agnarr, but she is also secretly Northuldra. Ever since the day the forest fell, Arendellians have despised and distrusted Northuldra with a vengeance. No matter that the Northuldra—along with some of Arendelle’s own—have been trapped in the Enchanted Forest behind an impenetrable wall of mist since the day of the battle. Iduna doesn’t know why the mist refuses to part, or why it descended to begin with. The only clear thing is that she must keep her identity from everyone, even Agnarr. Her life depends on it. Fortunately for her, Agnarr doesn’t know that Iduna is the Northuldra girl he saw seemingly flying on a gust of wind all those years ago, the day of the celebration turned disaster. The day Agnarr lost his father, the king. The day Agnarr himself almost died. What Agnarr does know is that Iduna is a true ally in the face of his royal responsibilities and the expectations of an overbearing council and a well-meaning regent who will rule in Agnarr’s place until he turns twenty-one and assumes the Arendellian throne. As Iduna and Agnarr grow ever closer, however, friendship is no longer enough. If only falling for each other didn’t mean risking their futures: Iduna’s as a hidden-in-plain-sight citizen of Arendelle, and Agnarr’s as imminent king. But for a chance at true love, the risk might be worth taking

Studying Antarctica has never been for the fainthearted. "Hereabouts died a very gallant gentleman, Captain L. E. G. Oates of the Inniskilling Dragoons. In March 1912, returning from the Pole, he walked willingly to his death in a blizzard to try to save his comrades, beset by hardship." —Inscription on a cross placed near presumed final resting place of Antarctic explorer Lawrence “Titus” Oates, The Terra Nova Expedition, 1910-1913 “We have one survival bag for every two people.” —Antarctic paleontologist William Hammer, Transantarctic Vertebrate Paleontology Project, 2004 “When the ice cracks, it can sound like massive thunder rolls that seem to go on forever. If it is a serious cracking in the ice, it literally sounds like canon shots.” —Eighth-grade science teacher and Antarctic diver Robin Ellwood, Lake Ecosystems in Antarctica Project, 2008-2009 Humanity’s fascination with the land at the bottom of the globe dates back at least to the ancient Romans, who imagined Terra Australis Incognita—the “unknown southern land”—and drew it on their maps even though no one had ever seen it. It took a thousand years for this unknown land to become known. Despite the many people who have since visited it, conquering the Antarctic frontier is a never-ending challenge that calls scientists and explorers to risk their lives in the pursuit of knowledge. Frozen Secrets is the tale of a continent, the inside story of the critical, cutting-edge research that brave men and women from around the world have done and still do in Antarctica. Sally M. Walker traces expeditions from the earliest explorers to today’s research stations, where contemporary scientists work in some of the harshest conditions on Earth. Whether they study the formation of polar ice or the stratigraphy of ancient rock or the fossils of newly discovered dinosaurs or the chemistry of air trapped in miniscule frozen bubbles, the scientists working in Antarctica are building a body of knowledge that will influence future generations as they make choices that could affect the course of the whole planet.

When SCUBA instructor, Chris Ducham, discovers the skeletal remains of a NAZI U-boat captain, along with Enigma encoded documents, in a cave on Barbuda, his curiosity gets the better of him. He decides to put his carefree life as a connoisseur of the easy life on hold to unravel the mystery. News of his discovery soon reaches the ears of a secret society, The Skull and Bones, who wish to keep a secret hidden. Chris soon finds his life in danger and what started as a simple adventure, quickly turns into a battle of wits with a brotherhood with unlimited resources. Indeed it seems that he is up against former Presidents of the United States of America and ruthless corporations. Rather than submit to intimidation, he seeks to uncover what secret could be of such importance that it is worth killing for. And why could such powerful adversaries not simple destroy it, rather than try to hide it?

Earth's past is littered with the mysterious and unexplained: the pyramids, Easter Island, Stonehenge, dinosaurs, and the list goes on and on as science looks for clues to decipher these puzzles.One such mystery surrounds the now-extinct creature called the woolly mammoth. Author and meteorologist Michael Oard has studied the mammoth and its equally mysterious time period, the Ice Age, for many years and has come to some fascinating conclusions to help lift the fog engulfing the facts. Some of the questions he addresses include:What would cause the summer temperatures of the northern United States and European to plummet more than 50 degrees Fahrenheit?Why did mammoths become extinct across the entire earth at the same time as many other large mammals?Why are the mammoth carcasses found generally in standing positions?How could large lakes exist in what are today very dry, desert-like places?What was the source of the abnormal of moisture necessary for heavy snow?What caused the cold summer temperatures and heavy snowfall to persist for hundreds of years?In logical progression many other Ice Age topics are explained including super Ice Age floods, ice cores, man in the Ice Age, and the number of ice ages. This is one of the most difficult eras in geological history for a uniformitarian scientist (one who believes the earth evolved by slow processes over millions of years) to explain, simply because long ages of evolution cannot explain it. Provided here are plausible explanations of the seemingly unsolvable mysterious about the Ice Age and the woolly mammoths - Frozen in Time.

Anna, Queen of Arendelle, has been tirelessly preparing for the Polar Night's Celebration that is held every year to welcome the time when the sun doesn't rise in the Polar Circle. She has been working so hard, her fiancé Kristoff suggests she take a night off to visit her sister Elsa, the Snow Queen. Anna loves the idea. Accompanied by Kristoff, Sven, and Olaf, Anna reunites with Elsa in the Enchanted Forest. After telling spooky stories around the campfire, Olaf swears that one of the creatures of their tales has come to life! Who else is responsible for the sudden onset of storms and the earlier than normal darkening of the skies? Why else is everyone starting to become so forgetful? Anna and Elsa join forces to determine what is going on. Together they recall Kristoff's terrifying tale about a princess who turned into a draugr—an undead creature that steals memories in an effort to make others forget the misdeeds it committed when it was alive. Is it possible that Kristoff inadvertently unearthed memories of a draugr, and thus unleashed the monster upon Arendelle? Anna and Elsa must uncover the real story behind the tale before everyone in Arendelle forgets who they are and is cast into darkness forever....
