Plunge into the action when an ancient mystery returns. People vanish or die in strange circumstances, but some survive and return home. As the survivors attempt to resume a normal life, events force them to accept the undeniable truth. Werewolves, elves, dark elves, and other supernatural creatures exist. They also discover that their contact with these myths and legends has altered them in ways they don't yet understand. How they deal with this knowledge becomes a test of character. For good or evil, their choices serve as a catalyst for change on their home planet and the worlds they re-visit. While some civilisations exploit the situation, others strenuously resist impending revolution, but one question unites them all. Why is this happening? One ancient elven magician on a faraway world seeks answers as magic and science collide. Shadow Step offers adult and older teen readers exciting fantasy worlds, multiple characters and plenty of action.

From the bestselling author of Rich and Pretty comes a suspenseful and provocative novel keenly attuned to the complexities of parenthood, race, and class. Leave the World Behind explores how our closest bonds are reshaped—and unexpected new ones are forged—in moments of crisis. Amanda and Clay head out to a remote corner of Long Island expecting a vacation: a quiet reprieve from life in New York City, quality time with their teenage son and daughter, and a taste of the good life in the luxurious home they’ve rented for the week. But a late-night knock on the door breaks the spell. Ruth and G. H. are an older couple—it’s their house, and they’ve arrived in a panic. They bring the news that a sudden blackout has swept the city. But in this rural area—with the TV and internet now down, and no cell phone service—it’s hard to know what to believe. Should Amanda and Clay trust this couple—and vice versa? What happened back in New York? Is the vacation home, isolated from civilization, a truly safe place for their families? And are they safe from one other?

Using numerous mathematical and numerical techniques of diffraction theory, Waves in Focal Regions: Propagation, Diffraction and Focusing of Light, Sound and Water Waves provides a full and richly illustrated description of waves in focal regions. Unlike most books, the author treats electromagnetic, acoustic, and water waves in one comprehensive volume. After an introductory section, the book describes approximate diffraction theories and efficient numerical methods to study the focusing of various kinds of waves. It then covers the physical interpretation of the theories, their accuracy, and the computational savings obtained, emphasizing uniform asymptotic results that remain valid in the vicinity of shadow boundaries and caustics. The next part deals with the focusing of scalar waves, including thorough theoretical analyses and detailed contour maps of diffraction patterns in focal regions for a variety of different system parameters, such as f-number, Frensel number, aperture shape, amplitude distribution, and wavefront aberration. The author proceeds to explore the diffraction and focusing of electromagnetic waves. First solutions are derived for fields radiated by sources, reflected and refracted at plane interfaces, or diffracted by apertures in plane screens, and then these solutions are applied to study the focusing in homogeneous media and through a plane dielectric interface. In both cases, the author includes many computed results of the electromagnetic field distribution near focus. Presenting both theoretical and experimental results, the following part examines the focusing of sound and water waves by means of zone-plate lenses. The book concludes with a detailed study of the diffraction and focusing of water waves and a comparison of the results of both linear and nonlinear theories with those of experiments.

One of the feature stories of the Cthulhu Mythos, "The Shadow Out of Time" is the tale of a professor of political economics that is thrown into a mind-shattering journey through time and space, while his body is held hostage by an alien mind. Horrified and panic-stricken by the implications of his experiences, he hopes against all reason and evidence that he has merely lost his mind.

This textbook is intended for a course in electromagnetism for upper undergraduate and graduate students. The main concepts and laws of classical macroscopic electrodynamics and initial information about generalized laws of modern electromagnetics are discussed, explaining some paradoxes of the modern theory. The reader then gets acquainted with electrodynamics methods of field analysis on the basis of wave equation solution. Emission physics are considered using an example of the Huygens-Fresnel-Kirchhoff canonic principle. The representation about strict electrodynamics task statement on the base of Maxwell equations, boundary conditions, emission conditions and the condition on the edge is given. Different classes of approximate boundary conditions are presented, which essentially simplify understanding of process physics. The canonic Fresnel functions are given and their generalization on the case of anisotropic impedance. The free waves in closed waveguides and in strip-slotted and edge-dielectric transmission lines are described. A large number of Mathcad programs for illustration of field patterns and its properties in different guiding structures are provided. The material is organized for self-study as well as classroom use.

On one side, the Night World, rules by the Blood Lords and the Beast Kind. On the other, the elusive Fae and the humans, protected by their steadfast mages... Born a wraith, Lily is a shadow who slips between worlds. Brought up by a Blood Lord and raised to be his assassin, she is little more than a slave. But when Lily meets her match in target Simon DuCaine, the unlikely bond that develops between them threatens to disrupt an already stretched peace in a city on the verge of being torn apart...
