    First, he lost a pair of Oakley sunglasses. Second, he saved the life of President Ulysses S. Grant.It's the near future, and the technology exists to open doorways into the past--but not our past, not exactly. Each "past" is effectively an alternate world, identical to ours but only up to the date on which we access it. And a given "past" can only be reached once. After a passageway is open, it's the only road to that particular past; once closed, it can't be reopened.A passageway has been opened to a version of late 19th-century Ohio. It's been in operation for most of a decade, but it's no secret, on either side of time. A small city has grown up around it to entertain visitors from our time, and many locals earn a good living catering to them. But like all such operations, it has a shelf life; as the "natives" become more sophisticated, their version of the "past" grows less attractive as a destination.Jesse Cullum is a native. And he knows the passageway will be closing soon. He's fallen in love with a woman from our time, and he means to follow her back--no matter whose secrets he has to expose in order to do it.

    In Tom Barren's 2016, humanity thrives in a techno-utopian paradise of flying cars, moving sidewalks, and moon bases, where avocados never go bad and punk rock never existed . . . because it wasn't necessary. Except Tom just can't seem to find his place in this dazzling, idealistic world, and that's before his life gets turned upside down. Utterly blindsided by an accident of fate, Tom makes a rash decision that drastically changes not only his own life but the very fabric of the universe itself. In a time-travel mishap, Tom finds himself stranded in our 2016, what we think of as the real world. For Tom, our normal reality seems like a dystopian wasteland. But when he discovers wonderfully unexpected versions of his family, his career, and—maybe, just maybe—his soul mate, Tom has a decision to make. Does he fix the flow of history, bringing his utopian universe back into existence, or does he try to forge a new life in our messy, unpredictable reality? Tom’s search for the answer takes him across countries, continents, and timelines in a quest to figure out, finally, who he really is and what his future—our future—is supposed to be.

    Suddenly the planet and every living thing on it no longer exist in a single timeline. Instead, the world becomes a patchwork of eras, from prehistory to 2037, each with its own indigenous inhabitants.Scattered across the planet are floating silver orbs impervious to all weapons and impossible to communicate with. Are these technologically advanced devices responsible for creating and sustaining the rifts in time? Are they cameras through which inscrutable alien eyes are watching? Or are they something stranger and more terrifying still?The answer may lie in the ancient city of Babylon, where two groups of refugees from 2037: three cosmonauts returning to Earth from the International Space Station, and three United Nations peacekeepers on a mission in Afghanistan have detected radio signals: the only such signals on the planet, apart from their own. The peacekeepers find allies in nineteenth-century British troops and in the armies of Alexander the Great. The astronauts, crash-landed in the steppes of Asia, join forces with the Mongol horde led by Genghis Khan. The two sides set out for Babylon, each determined to win the race for knowledge . . . and the power that lies within.Yet the real power is beyond human control, perhaps even human understanding. As two great armies face off before the gates of Babylon, it watches, waiting. . . .

Jain and her JSC team realize that their routine geological survey of a Martian cave system is anything but.
