Her mind tried to fight a bloody battle against what her body already knew. She wanted him, and she wanted him bad. On the heels of college graduation and the unexpected death of her mother, Emily Cooper moves to New York City to join her boyfriend for a fresh start. Dillon Parker has been sweet, thoughtful, and generous through Emily’s loss, and she can’t imagine her life without him—even as her inner voice tells her to go slow. Then she meets Gavin Blake. A rich and notorious playboy, Gavin is dangerously sexy and charming as hell. Their first encounter is brief, but it’s enough to inflame Emily’s senses. When their paths cross again through an unexpected mutual acquaintance, she tries to deny the connection she feels, but Mr. Tall, Dark, and Handsome won’t let go so easily. As she discovers Gavin’s pain-filled past and Dillon’s true nature begins to surface, Emily knows she must take action or risk destroying everyone—including herself. But how can she choose when she can’t trust her own heart?

A race against time, war, and the very fabric of the universe itself, perfect for fans of Sliding Doors and 11/22/63. Sixteen-year-old Winnie Schulde has always seen splits--the moment when two possible outcomes diverge, one in her universe and one in another. Multiverse theory, Winnie knows, is all too real, though she has never been anything but an observer of its implications--a secret she keeps hidden from just about everyone, as she knows the uses to which it might be put in the midst of a raging WWII. But her physicist father, wrapped up in his research and made cruel by his grief after the loss of Winnie's mother, believes that if he pushes her hard enough, she can choose one split over another and maybe, just maybe, change their future and their past. Winnie is certain that her father's theories are just that, so she plays along in an effort to placate him. Until one day, when her father's experiment goes wrong and Scott, the kind and handsome lab assistant Winnie loves from afar, is seriously injured. Without meaning to, Winnie chooses the split where Scott is unharmed. And in doing so, finds herself pulled into another universe, an alternate reality. One that already has a Winnie. In this darkly thrilling novel that blends science and war with love and loss, some actions just can't be undone. Praise for When You and I Collide: "A serious tale of attempting reinvention at the cost of rending reality." --Kirkus Reviews

"A fantastic end to this series!" –Erin Arkin, Fiction Fare Ari Alexander is now back on Earth, and the world she left behind has been turned upside down. A new leader has risen to power, her friends have become her enemies, and Jackson is thought to be trapped on Loge with her archrival, Zeus. Now Ari must determine who is the true enemy before Zeus attacks and Earth is forced into a battle of the dominant species. Will Ari and Jackson's love give them the strength to survive the greatest war in human history? The Taking series is best enjoyed in order.

Scientists are building rocket ships for a chosen few to escape planets hurtling toward each other on a direct collision course, leaks out touching off a savage struggle for survival.

Starting with novel algorithms for optimally updating bounding volume hierarchies of objects undergoing arbitrary deformations, the author presents a new data structure that allows, for the first time, the computation of the penetration volume. The penetration volume is related to the water displacement of the overlapping region, and thus corresponds to a physically motivated and continuous force. The practicability of the approaches used is shown by realizing new applications in the field of robotics and haptics, including a user study that evaluates the influence of the degrees of freedom in complex haptic interactions. New Geometric Data Structures for Collision Detection and Haptics closes by proposing an open source benchmarking suite that evaluates both the performance and the quality of the collision response in order to guarantee a fair comparison of different collision detection algorithms. Required in the fields of computer graphics, physically-based simulations, computer animations, robotics and haptics, collision detection is a fundamental problem that arises every time we interact with virtual objects. Some of the open challenges associated with collision detection include the handling of deformable objects, the stable computation of physically-plausible contact information, and the extremely high frequencies that are required for haptic rendering. New Geometric Data Structures for Collision Detection and Haptics presents new solutions to all of these challenges, and will prove to be a valuable resource for researchers and practitioners of collision detection in the haptics, robotics and computer graphics and animation domains.

Written by an expert in the game industry, Christer Ericson's new book is a comprehensive guide to the components of efficient real-time collision detection systems. The book provides the tools and know-how needed to implement industrial-strength collision detection for the highly detailed dynamic environments of applications such as 3D games, virtual reality applications, and physical simulators. Of the many topics covered, a key focus is on spatial and object partitioning through a wide variety of grids, trees, and sorting methods. The author also presents a large collection of intersection and distance tests for both simple and complex geometric shapes. Sections on vector and matrix algebra provide the background for advanced topics such as Voronoi regions, Minkowski sums, and linear and quadratic programming. Of utmost importance to programmers but rarely discussed in this much detail in other books are the chapters covering numerical and geometric robustness, both essential topics for collision detection systems. Also unique are the chapters discussing how graphics hardware can assist in collision detection computations and on advanced optimization for modern computer architectures. All in all, this comprehensive book will become the industry standard for years to come.
