Earth is no longer home. Rob and his family are no longer safe on their home planet, nor are their brethren. Humans are now aware of the telepaths and the declining fertility rate of the human population. Only 2.5 million have emigrated from earth out of the 100 million that had mutated since the first of the coronavirus vaccines came available on December 11, 2020, and space travel became possible in 2055. It is now 2056 and there are only 14 years left to get most of the rest of the telepaths off the earth.

Tellus is a constant reminder of what will happen if the telepaths remain on earth. The humans who had lived on Tellus before the recent immigrants had committed suicide following the path of the seven deadly sins. The telepaths will trigger the mass extinction event if they remain. It happened here because the two species couldn't live in harmony. It happened because the seven deadly sins can't exist in a world of telepaths.

Rob and his family are tasked with atoning for the sins of their predecessors, and recovering what is left of humanity. It's the last gasp for the former worlds whose ancestors were from Tellus, including Earth.
