It is 2065, and a year has passed since the people of Earth formally established relations with several extraterrestrial races. Appearances suggest that a new age of peace, economic prosperity, and enlightenment has begun.

One group of aliens in particular, the Greys, are an advanced and peaceful race. Human journalist C. A. Wyatt is in the process of writing a book about the Greys' odyssey from their home world, planet Zeta, to Earth and their crash landing near Roswell, New Mexico, in 1947. Their journey begins with the invasion of Zeta in 1944 by an aggressive alien species called Reptoids, just as the Greys' spaceship, Zeta's Hope, is about to be launched on an expedition to the uninhabited planet of Avalonia with fifty colonists—made up of both Greys and their human-like allies from planet Amigo. As crew of the ship voyages to various planets, they face a variety of problems, both internal and external, but eventually they set out to meet the humans of Earth, hoping for form a new alliance. But when those plans go awry, the fates of the Greys and of humanity will change forever.

In this science fiction novel, set in 2065, aliens known as Greys recall their journey to Earth in the 1940s through interviews with a human journalist.
