Through the thirteen novels, Elizabeth Stanton and her group discover what is actually happening on their world of Tarra. Namely, the aliens created Tarra as a dumping ground for all their own spiritual beings that they found objectionable in their societies - those who upset their societies: scientists, revolutionaries, artists, great thinkers, and of course criminals. Thus, these three different alien societies dumped these unwanted beings on Tarra, their penal colony, forcing the beings into physical bodies with enough traumas so that the beings could not leave the bodies (until it died), were convinced that they were nothing more than a physical body, and could not remember their previous lives. Stanton and her group reverse all of this over many hundreds of years, drive out the aliens, and develop a therapy to undo this horrific damage to the people, set against the long term evolution of the many societies on Tarra. This is the sixth novel in the Elizabeth Stanton series. With the invention of the fast caravel, she embarks on an exploration of the entire world, becoming the first to sail around the world. They encounter many new civilizations that were totally unknown to the known world. However, always in mind is their mission to track down any surviving Grey Creatures or mantis monsters, who have been inflicting pain and aberrations upon the people of Tarra, and destroy them. Shocking is an understatement for what they find in many of these new lands. The many surviving mantis creatures are still active, brutalizing women. One by one, the explorers rescue numerous people who are in dire need, taking them to the safety of the Santi fortresses and the rehabilitation facilities of the Laird Foundation. As they nearly finish their voyages of discovery, they again run into more of the mantis creatures. This time, Elizabeth herself becomes a victim of their brutality. Yet, she recovers and continues her fight against these despicable aliens. However, few actually suspect the magnitude of the aberrations that these creatures have imbedded within the subconscious minds of the inhabitants of Tarra.
