Post-Apocalyptic Science FictionIn the early twenty-first century catastrophe strikes, shattering the Earth's timelines and leaving in its wake a bleak, post-apocalyptic future. The world realigns. With past and future fractured, communities desperately cluster together for protection from marauding War Clans and predatory Scythers. Humanity is under attack from the worst enemy it's ever faced: humankind itself. In this climate of terror, a new breed of enforcer is needed-the Keepers.

Two men. One conspiracy. No time to waste.It's post-Brexit London, and the City is awash with illicit funds. With the country's security apparatus reeling from a lack of intelligence and operational capacity, an international terrorist with powerful mob connections seizes an opportunity to hack in and cash out. And now, it's only London's finest discretion consultants that stand between him and the City's utter demise.Bestriding London's subculture scene has led to experiences of a lifetime for discretion consultants Horrace Keyes and 'Fullon' Willy Watson. But when a menacing underworld boss approaches them, looking for dirt on a fast-rising politician, they are thrust into a maelstrom of terrorism, politics, and the murky world of high finance. What was once a wild and carefree existence is now a whirlwind of conspiracy, intrigue, and death.Keyes and Watson need to use their hard-kept secrets to survive, but doing so could kill them. The stakes are high. The clock is ticking. Game on.

As computer technology is used to control critical systems to an increasing degree, it is vital that the methods for developing and understanding these systems are substantially improved. The mathematical and scientific foundations currently used are extremely limited which means that their correctness and reliability cannot be ensured to an acceptable level. Systems engineering needs to become a fully fledged scientific discipline and formal methods, which are characterised by their firm mathematical foundations, are playing a vital role in achieving this transition. This volume is based on the proceedings of the Formal Methods Workshop (FM91), held in Drymen, Scotland, 24-27 September 1991. This was the second workshop sponsored by the Canadian and US governments to address the role of formal methods in the development of digital systems. Traditionally, formal methods have evolved in isolation from more conventional approaches, and one of the aims of this workshop was to emphasise the benefits of integrating the two areas. The workshop concentrated on the themes of quality assurance, design methods and mathematical modelling techniques. Particular emphasis was given to safety and security applications. Among the topics covered in this volume are: what is a formal method?; social research on formal methods; current quality assurance methods and formal methods; a pragmatic approach to validation; integrating methods in practice; composition of descriptions; and topics in large program formal development. Formal Methods in Systems Engineering provides an overview of many of the major approaches to formal methods and the benefits which can result from them. It is relevant to academic and industrial researchers, industrial practitioners and government workers with an interest in certification.
