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.

After bringing down the Lightning Nest, the heroes of THE RAT AND THE RAVEN have returned to the University, only to find it deserted and the gates locked. Dismas, who can break any lock, opens the outer door and they gain entry, but then they find that they are locked in and now not even Dismas can open the doors. Who is Emmanuel and how is it that he seems able to control their thoughts? Locked in the tower, the Ravens must fight to defend everything that is most precious – their very humanity is at risk. Emmanuel wants desperately to become human and needs to overwhelm and inhabit them to ensure his own survival.

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.

The seemingly normal fourteen-year-old Bobby Pendragon is swept into an alternate dimension and becomes a Traveler, and it is up to him to travel from place to place to save not just Earth but the entire universe from the evil Saint Dane.

Once upon a time, in a parallel universe, there existed the continent of Triton… The Beast has risen! Airen is at war. The queen is dead. The coven is incomplete. And things are uncertain under the sea. Now, the unicorns and mermaids and witches and warriors and the strangers from other lands all must band together to face The Beast and save Triton. The unions have been realized. Silence and Mars, True and Farah, Cassius and Elena and Aramus and Ha-Lah are at their fullest powers. But the gods require sacrifice. The sacrifice of pure love. If it isn’t given, the Beast will prevail, and Triton will fall. It cannot be escaped; they must use all their might and magic… The Rising is nigh!

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.
