Romance and action come crashing together in Susan Adrian's Tunnel Vision in which a teenage boy with incredible powers is brought to the attention of the government. Jake Lukin just turned 18. He's decent at tennis and Halo, and waiting to hear on his app to Stanford. But he's also being followed by a creep with a gun, and there's a DARPA agent waiting in his bedroom. His secret is blown. When Jake holds a personal object, like a pet rock or a ring, he has the ability to "tunnel" into the owner. He can sense where they are, like a human GPS, and can see, hear, and feel what they do. It's an ability the government would do anything to possess: a perfect surveillance unit who could locate fugitives, spies, or terrorists with a single touch. Jake promised his dad he'd never tell anyone about his ability. But his dad died two years ago, and Jake slipped. If he doesn't agree to help the government, his mother and sister may be in danger. Suddenly he's juggling high school, tennis tryouts, flirting with Rachel Watkins, and work as a government asset, complete with 24-hour bodyguards. Forced to lie to his friends and family, and then to choose whether to give up everything for their safety, Jake hopes the good he's doing—finding kidnap victims and hostages, and tracking down terrorists—is worth it. But he starts to suspect the good guys may not be so good after all. With Rachel's help, Jake has to try to escape both good guys and bad guys and find a way to live his own life instead of tunneling through others.

In 1936, when he was just twenty-four years old, Alan Turing wrote a remarkable paper in which he outlined the theory of computation, laying out the ideas that underlie all modern computers. This groundbreaking and powerful theory now forms the basis of computer science. In Turing's Vision, Chris Bernhardt explains the theory, Turing's most important contribution, for the general reader. Bernhardt argues that the strength of Turing's theory is its simplicity, and that, explained in a straightforward manner, it is eminently understandable by the nonspecialist. As Marvin Minsky writes, "The sheer simplicity of the theory's foundation and extraordinary short path from this foundation to its logical and surprising conclusions give the theory a mathematical beauty that alone guarantees it a permanent place in computer theory." Bernhardt begins with the foundation and systematically builds to the surprising conclusions. He also views Turing's theory in the context of mathematical history, other views of computation (including those of Alonzo Church), Turing's later work, and the birth of the modern computer. In the paper, "On Computable Numbers, with an Application to the Entscheidungsproblem," Turing thinks carefully about how humans perform computation, breaking it down into a sequence of steps, and then constructs theoretical machines capable of performing each step. Turing wanted to show that there were problems that were beyond any computer's ability to solve; in particular, he wanted to find a decision problem that he could prove was undecidable. To explain Turing's ideas, Bernhardt examines three well-known decision problems to explore the concept of undecidability; investigates theoretical computing machines, including Turing machines; explains universal machines; and proves that certain problems are undecidable, including Turing's problem concerning computable numbers.

Love often seems uncontrollable and irrational, but we just as frequently appear to have reasons for loving the people we do. In Love's Vision, Troy Jollimore offers a new way of understanding love that accommodates both of these facts, arguing that love is guided by reason even as it resists and sometimes eludes rationality. At the same time, he reconsiders love's moral status, acknowledging its moral dangers while arguing that it is, at heart, a moral phenomenon--an emotion that demands empathy and calls us away from excessive self-concern. Love is revealed as neither wholly moral nor deeply immoral, neither purely rational nor profoundly irrational. Rather, as Diotima says in Plato's Symposium, love is "something in between." Jollimore makes his case by proposing a "vision" view of love, according to which loving is a way of seeing that involves bestowing charitable attention on a loved one. This view recognizes the truth in the cliché "love is blind," but holds that love's blindness does not undermine the idea that love is guided by reason. Reasons play an important role in love even if they rest on facts that are not themselves rationally justifiable. Filled with illuminating examples from literature, Love's Vision is an original examination of a subject of vital philosophical and human concern.
