Terra is overcrowded, but a solution may have been found -- tucked away in Roswell is alien technology that leads to the creation of a method of space travel known as portaling .

A party of soldiers and scientists led by Dr. Emma Bradley, Colonel John Berger, and Dr. Layton Tremayne are about to take what they believe is the first step into the unknown. But what they discover is not only a wonder but a puzzle. The city of Eden on the distant planet Nibiru has obvious Terran influences. Who was there before them?

When Emma, John, and Layton return to Terra, they're dismayed to find things are even worse than they were when the trio left. The atmosphere is on the verge of toxicity and the population is reaching Malthusian proportions. Worse, there are plans afoot to portal the excess population off Terra to planets which may not be what their new inhabitants expect. Most won't survive.

Then they learn that a platoon of soldiers were portaled to Eden for a planned invasion of Nibiru and the surrounding planets. Emma, John, and Layton scramble to stop the military action, but will they be able to take back the city that’s become their home?
