Book Description
Games that show how mathematics can solve the apparently unsolvable. This book presents a series of engaging games that seem unsolvable--but can be solved when they are translated into mathematical terms. How can players find their ID cards when the cards are distributed randomly among twenty boxes? By applying the theory of permutations. How can a player guess the color of her own hat when she can only see other players' hats? Hamming codes, which are used in communication technologies. Like magic, mathematics solves the apparently unsolvable. The games allow readers, including university students or anyone with high school-level math, to experience the joy of mathematical discovery.

Book Description
Hunted. Hidden. Scattered. But the old bloodlines hold true. And now is the time of the Rising. It’s been a hundred years since the Shade King orchestrated the Fall of the Graced; a century since he tipped the balance in his favour and brought those magically gifted warriors to their knees. But now a new power is rising and even the faintest ember, buried amongst ash and ruin, can reignite the flames of war. Renila remembers nothing of her life before the birth of her son, save the old stories she knows by heart. But when a stranger arrives at the castle she calls home, her past begins to resurface – and with it, her power. Enslaved by his master’s dark magic, the Shade King’s general, Alexan, has been dispatched to hunt down the King’s daughter – and either return her to her father, or kill her. His history with the Princess makes him well suited to the task, but it may also be his undoing. Keriath, bastard daughter of the Shade King, has been hunted her entire life and, since she was old enough to wield the power in her veins, has dedicated herself to destroying the monster who claims to have sired her. But the events of a single night may change her fate forever. The twins, Lucan and Suriya, are plagued by nightmares – by visions of myth and monsters – for which their mysterious yet domineering mother blames Renila and her stories. But there is something she is not telling them, and they are determined to find out what. This enthralling and immersive epic fantasy story is the first in the Rising Series, and Jen McIntosh’s debut novel.

Book Description
A matchless warrior is pitted against a near-God in the second epic installment of the Raven’s Blade series. It has long been our lot in life, brother, to do what others can’t. Vaelin Al Sorna was known across the realm as the greatest of warriors, but he thought battles were behind him. He was wrong. Prophecy and rumor led him across the sea to find a woman he once loved, and drew him into a war waged by the Darkblade, a man who believes himself a god—and one who has gathered a fanatical army that threatens all of the known world. After a costly defeat by the Darkblade, Vaelin’s forces are shattered, while the self-proclaimed immortal and his army continue their terrible march. But during the clash, Vaelin regained some of the dark magic that once gave him unrivaled skill in battle. And though the fight he has been drawn into seems near unwinnable, the song that drives him now desires the blood of his enemy above all else…

Book Description
The people of Ledford cherish the mysterious island of blue-eyed crows and ravens in the midst of the big river that cuts their city in two. The island-uninhabited since the days of the old hermit for whom it was named-beckons outcast Jesuit scholar and ornithologist Alfredo Manzi to its dark forest. He meets Charlie, a blue-eyed crow who seems to be expecting him. The crow tells Manzi he is one of the last of the Patua', a Homo sapien subspecies with a strange ability to verbally communicate with the corvids, a group of highly intelligent birds that includes ravens and crows. Manzi learns to his growing amazement that he is not the first of his kind to visit Wilder Island, and that it holds many secrets of his ancient, vanishing race. The corvids put all hope upon him to bring the Patua' back from the edge of oblivion and save the Earth from the ravages of human technology. But the island itself is in grave danger of a takeover from a land developer whose plans will most certainly destroy the unique corvid population forever, as well the legacy of the Patua'. Manzi begins fulfilling his mission to save the enchanted wilderness, enlisting help from the corvids, another Patua', and a colleague and his wife, who is about to uncover her own secrets. In this fantasy tale, corvids and humans must band together to save their beloved island from destruction-before it is too late.

Book Description
Two brothers struggling to find their place in the world. For the elder sibling Kildare, every morning begins with the memory of betrayal. Once governed by the principles of morality, Kildare has become an instrument of blood and steel-where the speed of his sword arm metes out his own brand of justice. Only the strength and resolve of his brother Zedaine keeps him from succumbing to the ever-present rage that burns behind his dark eyes. While employed by the mysterious sage Blade, the pair stumble upon Chameleon, a runaway tribeswoman displaying extraordinary psychic powers. Their meeting, however, is no chance encounter. A riddle Chameleon carries will change not only the future of the three, but the fate of the entire world. Hundreds of miles away, Macklore, a powerful wizard of Brisbane, has been dispatched to the volatile city of Gallanse. Smitten at the sight of princess Lydia, Macklore defies his orders and finds himself thrust into the middle of a bloody succession. When he openly supports Lydia's family, he is marked for death by a cult of magi working to raise the psychotic prince Dragomir to the throne. With few allies, Macklore must use his wits and innate magical powers to keep Dragomir from the crown and himself alive. Racing towards Gallanse, Kildare and Zedaine are torn between saving Macklore's life and exacting terrible vengeance upon the man responsible for their betrayal.
