"From the moment the Hourglass group violated the rules of the space time continuum to rescue a murdered loved one, time has been in flux. People from other centuries slide into our time, intruding into our space, threatening our world. Frantically seeking a way to turn back this tide, the Hourglass begins a search for the legendary Infinityglass, tracking it to the city of New Orleans, a place where the past rests easily with the present. Quiet, reliable Dune, the group's favorite geek, is selected to travel to the Crescent City and somehow retrieve the renowned object. But there's a problem. Because the Infinityglass is not an object, it's a person. A beautiful, headstrong dancer named Hallie, a girl so enticing Dune can't take his eyes off her. And time is not on her side."--Jacket.

Official Summary: After what seemed like a lifetime of waiting, the Remnants are back on Earth -- for better or worse. Yago has taken control of Mother and stranded the Remnants along with their ruthless enemies the Riders and Meanies to keep them company. Meanwhile, Jobs discovers that Earth has some ‘remnants’ of its own humans who don’t know any world other than the new Earth. Will the survivors of the Rock help the remaining Remnants? Or does a new enemy lurk on the horizon? Back-of-Book Summary: The Remnants have rediscovered Earth. But it's definitely not the earth they left behind more than 500 years ago. It's not the earth that was almost completely destroyed by an asteroid. Everything that's left is in ruins, and there doesn't seem to be any water or food. Jobs, Mo'Steel, Billy, and the others have to try to find a way to make this wasteland into a home. They don't have a lot of supplies. . . . or time. And there are devastating storms that stir up intense winds -- and horrible dreams. Dreams that are almost real. What the Remnants don't know is there's something beneath the surface of the ravaged planet. Something they never could have imagined. And it could give Jobs and the others the chance they'd been hoping for. The chance to survive.
