This book demonstrates how nonlinear/non-Gaussian Bayesian time series estimation methods were used to produce a probability distribution of potential MH370 flight paths. It provides details of how the probabilistic models of aircraft flight dynamics, satellite communication system measurements, environmental effects and radar data were constructed and calibrated. The probability distribution was used to define the search zone in the southern Indian Ocean. The book describes particle-filter based numerical calculation of the aircraft flight-path probability distribution and validates the method using data from several of the involved aircraft’s previous flights. Finally it is shown how the Reunion Island flaperon debris find affects the search probability distribution.

Before the sword in the stone, before the rise of Arthur, there was Igraine—the woman whose choices would shape the fate of Camelot. In this bold, feminist reimagining of Arthurian legend, Igraine steps out of the shadows of myth to reclaim her story—a tale forged in magic, betrayal, and the brutal cost of prophecy. Raised in the mystical traditions of Avalon, Igraine is more than just a princess—she's a force of nature. Her marriage to the Cornish War Duke Gorlois is one of rare passion and political unity, but when Gorlois turns his back on the old magic, cracks begin to form—not just in their bond, but in the fragile peace of Britain itself. At a royal gathering, King Uther Pendragon’s lust for Igraine ignites a firestorm. When he acts on his obsession, it triggers a chain of war and treachery that Merlin claims is foretold by prophecy: Igraine is fated to bear the Once and Future King. But destiny has a dark price. As kingdoms clash and alliances crumble, Igraine rises as the spiritual and political heart of Tintagel. She leads the women abandoned by war, trains her daughters—Morgause and Morgan—in the old ways, and dares to dream of a future shaped by women’s power. But on the eve of a sacred Solstice celebration, a devastating deception will force Igraine to confront the true cost of her fate. Chosen by the Goddess, the King, and prophecy—Igraine must ultimately choose herself. And with that choice, she will unleash a legacy of love and vengeance that echoes through the ages.

In the second in the Pendragon Prophecy series, Sam Davey plunges into the heart of the Camelot story and the fraught relationships between grown siblings Morgause, Morgan, and Arthur. A dark and mesmerizing retelling of Camelot—where magic and destiny entwine with sibling rivalries, forbidden love, and looming rebellion. One year after the death of Uther Pendragon, High King of Britain, a lavish tournament is held in his memory, and as an opportunity for the nobles and allies to swear another year’s fealty to King Lot of Orkney and his wife Queen Morgause. At the tournament, Arthur, an unknown youth, is seeking a replacement sword for his foster brother. He succeeds in pulling a mysterious sword from a stone anvil in the courtyard at Caer Lundein and is proclaimed King of all Britain. Merlin prepares the bewildered Arthur for kingship and reveals to Morgause that Arthur’s reign will end if he faces in battle a noble knight born at Beltane (May 1) in the first year of his reign. Morgan, a powerful priestess and sister to Morgause and Arthur, becomes Lady of the Lake– and she and Morgause, who blame Arthur for their violent and traumatic childhood, plot against him. Morgan, who has concealed her identity from Arthur, seduces her brother and becomes pregnant. At a grand Tournament and celebration in Caerleon, Merlin finally tells Arthur of the prophecy of the Beltane child, and Arthur is horrified to learn that Merlin can see no solution but to kill all of the noble children born on Beltane that year. Arthur tells Lot he will not follow Merlin’s advice, but when he discovers Morgan is actually his sister, he believes Lot has helped to deceive him and turns back to Merlin’s guidance. Lot joins the rebels, his four sons remaining loyal to Arthur, as the Once and Future King seals his fate.
