Peter Hobson has created three electronic simulations of his own personality. The first has all knowledge of physical existence edited out, to simulate life after death. The second is without knowledge of aging or death, to simulate immortality. The third is unmodified, a control. Now they are free. One is a killer.

    "You will forever be a child of two worlds, capable of choosing your own destiny. the only question you face is, which path will you choose?"

    Most genetic defects will be removed at birth; the remaining during infancy. Unfortunately, there will be a generation left behind. For members of that missed generation, small advances will be made. Through various programs, they will be taught to get along in the world despite their differences. They will be made active and contributing members of society. But they will never be normal.Lou Arrendale is a member of that lost generation, born at the wrong time to reap the awards of medical science. Part of a small group of high-functioning autistic adults, he has a steady job with a pharmaceutical company, a car, friends, and a passion for fencing. Aside from his annual visits to his counselor, he lives a low-key, independent life. He has learned to shake hands and make eye contact. He has taught himself to use “please” and “thank you” and other conventions of conversation because he knows it makes others comfortable. He does his best to be as normal as possible and not to draw attention to himself. But then his quiet life comes under attack. It starts with an experimental treatment that will reverse the effects of autism in adults. With this treatment Lou would think and act and be just like everyone else. But if he was suddenly free of autism, would he still be himself? Would he still love the same classical music–with its complications and resolutions? Would he still see the same colors and patterns in the world–shades and hues that others cannot see? Most importantly, would he still love Marjory, a woman who may never be able to reciprocate his feelings? Would it be easier for her to return the love of a “normal”?There are intense pressures coming from the world around him–including an angry supervisor who wants to cut costs by sacrificing the supports necessary to employ autistic workers. Perhaps even more disturbing are the barrage of questions within himself. For Lou must decide if he should submit to a surgery that might completely change the way he views the world . . . and the very essence of who he is.Thoughtful, provocative, poignant, unforgettable, The Speed of Dark is a gripping exploration into the mind of an autistic person as he struggles with profound questions of humanity and matters of the heart.From the Hardcover edition.

    It is a lonely job, and a thankless one for the most part. Until something goes wrong. Until a ship is in distress. In the 23rd century, this job has moved into outer space. A network of beacons allows ships to travel across the Milky Way at many times the speed of light. These beacons are built to be robust. They never break down. They never fail. At least, they aren't supposed to.

    Lovecraft established the genuineness and dignity of his own pioneering fiction in 1931 with his quintessential work of supernatural horror, At the Mountains of Madness.

    Yes, that seemed normal enough---but what was this talk about "death trauma"?Thus was Thomas Blaine introduced to the year 2110, where science had discovered the technique of transferring a man's consciousness from one body to another. Where a man's mind could be snatched from the past, when his body was at the point of death, and brought forward into a "host body" in this fantastic future world. But that was only a small part of it. For the future had proved the reality of life after death, and discovered worlds beyond or simultaneous with our own---worlds where, through scientific techniques, a man could live again, in another body, when he died here. And in the process, the reality of ghosts, poltergeists, and zombies was also established. What did it all mean? How had this discovery of what they called the "hereafter" shaped the world of 2110? Thomas Blaine found himself living in a future where the discoveries and techniques imagined by people of his time, while having come about, were completely overwhelmed by discoveries no one had ever dreamed of.
