Infernal Devices


K.W. Jeter - 1986
    But idle sometime-musician George has little talent for clockwork. And when a shadowy figure tries to steal an old device from the premises, George finds himself embroiled in a mystery of time travel, music and sexual intrigue. A genuine lost classic, a steampunk original whose time has come.

The Wild Shore


Kim Stanley Robinson - 1984
    For the small community of San Onofre on the West Coast, life is a matter of survival: living simply on what the sea and land can provide, preserving what knowledge and skills they can in a society without mass communications. Until the men from San Diego arrive, riding the rails on flatbed trucks and bringing news of the new American Resistance. And Hank Fletcher and his friends are drawn into an adventure that marks the end of childhood...

Orion


Ben Bova - 1984

Venus Plus X


Theodore Sturgeon - 1960
    Here, violence is a vague and improbable notion. Technology has triumphed over hunger, overpopulation, pollution, even time and space. But there is a change Charlie finds even more shocking: gender is a thing of the past. Venus Plus X is Theodore Sturgeon's brilliant evocation of a civilization for whom tensions between male and female and the human preoccupation with sex no longer exist. As Charlie Johns explores Ledom and its people, he finds that the human precepts he holds dear are profane in this new world. But has Charlie learned all there is to know about this advanced society? And why are the Ledom so intent on gaining Charlie's approval? Unsettling, compelling, and no less than visionary, here is science fiction at its boldest: a novel whose wisdom and lyricism make it one of the most original and insightful speculations on gender ever produced.

The Two-Timers


Bob Shaw - 1968
    If anyone needed incontrovertible proof that the fiction of wonder has come of age, Bob Shaw has provided it in one extraordinary novel of power, warmth, ideas and imagination. The Two-Timers says something fresh and memorable about the monomania of love, about the way we wear our universe, about a few of the eternal verities that suddenly seem less secure. Aside from the sheer impetus of the story, which grasps and won't release till the unexpected conclusion, the writing is exquisite. It knocked me cold: painfully good."Harlan Ellison

Time Salvager


Wesley Chu - 2015
    In his time, Earth is a toxic, abandoned world and humans have fled into the outer solar system to survive, eking out a fragile, doomed existence among the other planets and their moons. Those responsible for delaying humanity’s demise believe time travel holds the key, and they have identified James, troubled though he is, as one of a select and expendable few ideally suited for the most dangerous job in history. James is a chronman, undertaking missions into Earth's past to recover resources and treasure without altering the timeline. The laws governing use of time travel are absolute; break any one of them and, one way or another, your life is over. Most chronmen never reach old age; the stress of each jump through time, compounded by the risk to themselves and to the future, means that many chronmen rapidly reach their breaking point, and James Griffin-Mars is nearing his.On a final mission that is to secure his retirement, James meets Elise Kim, an intriguing scientist from a previous century, who is fated to die during the destruction of an oceanic rig. Against his training and his common sense, and in violation of the chronmen’s highest law, James brings Elise back to the future with him, saving her life, but turning them both into fugitives. Remaining free means losing themselves in the wild and poisonous wastes of Earth, somehow finding allies, and perhaps discovering what hope may yet remain for humanity's home world.
