Book 7 of the Two Worlds Epic
It is two centuries since a nuclear holocaust devastated the Earth. Friendly
humanoid aliens, the Reptons, rescued one thousand human survivors and
transported them to Tamacra, a Repton-inhabited world orbiting Tau Ceti. The
small human colony thrived over the next ten generations as they integrated
themselves into Repton society.
Meanwhile, Earth has returned to its former verdant glory and is now ripe for
recolonization, Greg Diltwood and Lissa Doltgren are heavily involved in a
decades-long effort to reseed the old home world. Their careful plans
are suddenly disrupted when astronomers discover a rogue planet on a
collision course with Tamacra.
With only 400 days left to transfer 5 billion Reptons and hundreds of thousands
of humans to Earth, they face a seemingly impossible task. Even the large
Repton interstellar fleet is inadequate to the task. The most optimistic
projections indicate there isn't enough time to save everyone. Greg and Lissa
face hard choices, as well as mortal danger, from the approaching rogue planet.
What are they to do?
