Two hundred years in the future regular human beings hate and fear the Sleepless and the SuperSleepless, genetically modified humans who are immune to disease and hunger, and need no sleep.

When Lara was twelve, and her younger brother Alfie eight, their father died in a helicopter crash. A prominent plastic surgeon, and Irishman, he had honed his skills on the bomb victims of the Troubles. But the family grew up used to him being absent: he only came to London for two weekends a month to work at the Harley Street Clinic, where he met their mother years before, and they only once went on a family holiday together, to Spain, where their mother cried and their father lost his temper and left early. Because home, for their father, wasn't Earls Court: it was Belfast, where he led his other life... Narrated by Lara, nearing forty and nursing her dying mother, All the Beggars Riding is the heartbreaking portrait of a woman confronting her past just as she realises that time is running out

In a world where the slightest edge can mean the difference between success and failure, Leisha Camden is beautiful, extraordinarily intelligent ... and one of an ever-growing number of human beings who have been genetically modified to never require sleep. Once considered interesting anomalies, now Leisha and the other "Sleepless" are outcasts -- victims of blind hatred, political repression, and shocking mob violence meant to drive them from human society ... and, ultimately, from Earth itself. But Leisha Camden has chosen to remain behind in a world that envies and fears her "gift" -- a world marked for destruction in a devastating conspiracy of freedom ... and revenge.

For most of his life, Newton McClintok had lived in the Americal flapper era. He might have been an ancient Roman or a Victorian Englishman.

After an unsuccessful suicide attempted, he embarked on a journey through the ages to find his own special Utopia -- only to discover that the journey never ends! A classic science fiction novel from the author of The Ecolog and TimeQuest.

In a comprehensive yet easy-to-follow manner, Discrete Mathematics for New Technology follows the progression from the basic mathematical concepts covered by the GCSE in the UK and by high-school algebra in the USA to the more sophisticated mathematical concepts examined in the latter stages of the book. The book punctuates the rigorous treatment of theory with frequent uses of pertinent examples and exercises, enabling readers to achieve a feel for the subject at hand. The exercise hints and solutions are provided at the end of the book. Topics covered include logic and the nature of mathematical proof, set theory, relations and functions, matrices and systems of linear equations, algebraic structures, Boolean algebras, and a thorough treatise on graph theory. Although aimed primarily at computer science students, the structured development of the mathematics enables this text to be used by undergraduate mathematicians, scientists, and others who require an understanding of discrete mathematics.
