This series of thirteen books shows the evolution over time of both societies and human aberrations, caused in no small part by the direct control of three different groups of aliens. The premise is that people are spiritual beings that inhabit physical bodies and have minds. Further, traumas block memories of past lives as well as inhibiting recall of previous lives and dictate in some measures the person's behavior in their current lifetime. The aliens aid in the forgetting process by latching onto the spiritual being whose current body has just died, electronically zapping them, scrambling and altering the memories in their mind, and then implanting commands to be obeyed in the next lifetime, such as "You are no good," "You are worthless," and "You are stupid." Thus the commands buried in these moments of pain and unconsciousness impact the person's next lifetime; the person will believe utterly that they are "no good" or that they are completely "worthless" or that they are incredibly "stupid."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.It is my own personal belief that such a notion of trauma blocking past memories may well be germane to our own world and people. Thus, I purposely intended for the reader to pick up on the allusions to the "Mediterranean Sea, the Sahara, Middle East, the Roman Empire and northern Europe," though with one exception, the rest of Tarra is vastly different. I hope this tends to make the reader ponder the idea that past traumas might be adversely affecting themselves and how it might actually work, as well as some hope for how such traumas might be uncovered and erased, as well as what the results of doing that might just be. Explore how aberration is created and propagated across lifetimes. Is this parallel to our own lives and world?This is the final novel in the Elizabeth Stanton series. All three alien races return to Tarra, dumping the last of their undesirable spiritual beings onto the penal colony. However, this time, the mantises handle the massive "prison break" before anyone discovers their presence, unleashing a worldwide plague that is designed to force all spiritual beings back into their prison cells. Once more, Bethany and her group eliminate these aliens, but are too late to prevent the plague from affecting everyone on Tarra.The results very nearly destroy all civilization on the planet, which enters a very Dark Age indeed. While Jes and his group work on erasing the traumas enabling the people to regain their native spiritual freedom and abilities, Bethany and her group work on salvaging the countries, one by one. By the end of the novel, the true native powers of a spiritual being become manifest, near godlike powers, offering true hope for mankind.
