They are the "Others," an ancient race of supernatural beings--magicians, shape-shifters, vampires, and healers--who live among us. Human born, they must choose a side to swear allegiance to--the Dark or the Light--when they come of age.

For a millennium, these opponents have coexisted in an uneasy peace, enforced by defenders like the Night Watch, forces of the Light who guard against the Dark. But prophecy decrees that one supreme "Other" will arise to spark a cataclysmic war.

Anton Gorodetsky, an untested mid-level Light magician with the Night Watch, discovers a cursed young woman--an Other of tremendous potential unallied with either side--who can shift the balance of power. With the battle lines between Light and Dark drawn, the magician must move carefully, for one wrong step could mean the beginning of annihilation.

The third book in Sergei Lukyanenko's dark and thrilling Night Watch series--a visionary blend of urban fantasY and riveting thriller, set in contemporary Moscow

Night Watch and Day Watch revealed the "Others," an ancient race of supernatural beings--magicians, shape-shifters, vampires, and healers--who live among us and swear allegiance to either the Dark or the Light. For a millennium, these opponents have coexisted in an uneasy truce, guarding each other and tottering on the brink of war.

In Twilight Watch, the Others face their greatest threat yet. An ancient book of spells with the power to turn ordinary humans into Others has fallen into the wrong hands, threatening to destroy the precarious balance between the forces of Darkness and Light. Now the Night Watch and the Day Watch must cooperate to stop the culprit. Anton, the hero from Night Watch, is back, but when the renegade Other turns out to be closer to home than he expected, the race to prevent global war becomes more urgent than ever. And as Anton gets closer to discovering the true nature of the Others, he begins to question how much of a difference there truly is between the Dark and the Light.

A frightening new danger arises to threaten the Twilight. . . .

For a millennium, the Others have maintained an uneasy peace that has protected them and the Twilight, a shadowy parallel world beneath our own. But the battle for supremacy between the forces of the Light and the Darkness is far from over. . . .

Now older and more powerful, Light magician Anton Gorodetsky has risen to the top levels of the Night Watch. He is also father to a ten-year-old girl who is destined to become a magician of unprecedented power. When he hears a young boy at the airport screaming that a plane will crash, Anton suspects the child is a prophet--a rare type of Other who portends catastrophe.

If Anton is right, then the boy has awakened a terrifying danger--a rare, multifaced beast that exists to stop the prophecy from coming true. With their lives in mortal peril and time running out, Anton must find a way to keep his gifted young daughter safe . . . and save the Twilight itself.

Historically, mathematics, probability, and statistics have been widely used in the biological sciences. Recent progress in genomics has yielded many millions of gene sequences. But what do these sequences tell us and what are the generalities and rules governed by them? It seems that we understand very little about the genetic contexts required to 'read' them. There is more to life than the genomic blueprint of each organism. Life functions within the natural laws that we know and the ones we do not know. The development of modern mathematical natural sciences is based on the use of certain mathematical tools. Mathematics can be used to understand life from the molecular to the biosphere level.This book provides the foundation and latest advances for an emerging research area that uses tools from symbolic computation, computer algebra and logic, algebraic geometry, fractal geometry, probability and statistics, and matrix algebra to formalize and solve biological problems and explore its applications in algebraic biology and code biology. It introduces highly interdisciplinary topics in biomathematics such as matrix genetics, gestalt biology, bio-antenna arrays, resonance genetics, quantum biology, and more.

This book focuses on the notion of the environmental sustainability of the economy. The Sustainable Development Goals, formulated by the UN, led to the formation of a concept of the environmental sustainability of the economy. This concept implies the harmony of economy and environment, achieved due to the support for the SDGs in the economy. This book is original due to its reconsidering the environmental sustainability of the economy from the position of crises.  The theoretical significance of the book consists in the development of an anti-crisis approach to the provision of the environmental sustainability of the economy: responsible nature use based on digital markets and smart governance. The proprietary approach allows for the comprehensive description of the potential of the leading technologies—artificial intelligence (AI), robots, the Internet of Things (IoT), and blockchain—to support—during their use in smart governance—crisis management of the environmental sustainability of economy. The book’s practical significance is due to the description and detailed discussion of the modern international experience of responsible nature use given the specifics of developed and developing countries. The anti-crisis approach to the provision of the environmental sustainability of the economy is based on digital markets: FinTech, EdTech, GovTech, AgroTech, and EnergyTech, the practice of which is described in the book with the help of multiple examples from the international experience and case studies. The book is aimed at scholars who study environmental economics. In this book, they find an innovative view of the environmental sustainability of the economy in its close connection with economic crises.

The term "stereotype space" was introduced in 1995 and denotes a category of locally convex spaces with surprisingly elegant properties. Its study gives an unexpected point of view on functional analysis that brings this fi eld closer to other main branches of mathematics, namely, to algebra and geometry. This volume contains the foundations of the theory of stereotype spaces, with accurate definitions, formulations, proofs, and numerous examples illustrating the interaction of this discipline with the category theory, the theory of Hopf algebras, and the four big geometric disciplines: topology, differential geometry, complex geometry, and algebraic geometry.
