For eons, Earth has been under observation by the Firstborn, beings almost as old as the universe itself. The Firstborn are unknown to humankind--until they act. In an instant, Earth is carved up and reassembled like a huge jigsaw puzzle. 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...

Bisesa Dutt tries to discover why she was returned to Earth in the year 2037 by the Firstborn amidst the turmoil of an approaching apocalypse.

Now, at the dawn of the twenty-third century, another ship is discovered hurtling toward us. A crew of Earth's best and brightest minds is assembled to rendezvous with the massive vessel. They are armed with everything we know about Raman technology and culture. But...

Having built a bridge across the Straits of Gibraltar, he dreams of an even greater accomplishment, a bridge to space: a "skyhook," or "space elevator." This will be a cable stretching from the Earth's equator to an anchoring satellite in geosynchronous orbit. First Morgan must deal with the monks who own the ideal real...
