More even than space travel, the Stileman Process has altered 21st-century life. The most complex of medical miracles, it ensures that every 10 years or so, the ailing aging body can be restored to youthful vigour and health. There's a catch, of course: the cost. Every 10 years or so, you have to come up with £1,000,000 minimum to repeat the procedure or die. For Dallas Barr, one of the oldest men on earth, it's that time again. While casting around desperately for his next essential £1,000,000, he meets Maria, a woman from a previous life, and makes two major discoveries.

We were fighting on the wrong side of a war we couldn't win. And that was the good news. The Ruhar hit us on Columbus Day. There we were, innocently drifting along the cosmos on our little blue marble, like the native Americans in 1492. Over the horizon come ships of a technologically advanced, aggressive culture, and BAM! There go the good old days, when humans only got killed by each other. So, Columbus Day. It fits. When the morning sky twinkled again, this time with Kristang starships jumping in to hammer the Ruhar, we thought we were saved.

Robert A. Heinlein wrote The Number of the Beast, which was published in 1980. In the book Zeb, Deety, Hilda, and Jake are ambushed by the alien "Black Hats" and barely escape with their lives on a specially configured vehicle (the Gay Deceiver) which can travel along various planes of existence, allowing them to visit parallel universes. However, unknown to most fans, Heinlein had already written a "parallel" novel about the four characters and parallel universes in 1977.

Two murders so closely linked in time and space must surely be connected.

The gigantic comet had slammed into Earth, forging earthquakes a thousand times too powerful to measure on the Richter scale, tidal waves thousands of feet high. Cities were turned into oceans; oceans turned into steam. It was the beginning of a new Ice Age and the end of civilization. But for the terrified men and women chance had saved, it was also the dawn of a new struggle for survival--a struggle more dangerous and challenging than any they had ever known....

For dinosaurs, it was a big rock. For humans: Coronal Mass Ejection (CME). When the Earth is hit by the greatest CME in recorded history (several times larger than the Carrington Event of 1859), the combined societies of the planet's most developed nations struggle to adapt to a life thrust back into the Dark Ages. In the United States, the military scrambles to speed the nation's recovery on multiple fronts including putting down riots, establishing relief camps, delivering medical aid, and bringing communication and travel back on line. Just as a real foothold is established in retaking the skies (utilizing existing commercial aircraft supplemented by military resources and ground control systems), a mysterious virus takes hold of the population, spreading globally over the very flight routes that the survivors fought so hard to rebuild.

Who have scattered Earth's last survivors. To stay alone is to stay alive, Cassie believes, until she meets Evan Walker. Beguiling and mysterious, Evan Walker may be Cassie's only hope for rescuing her brother - or even saving herself.
