Mars is for Martians: The Chronicles of Terraforming Mars

Mars is from Martian is a story of conflict between humans terraforming Mars and a race of Martians who have been genetically engineered to live in the Martian atmosphere. After a century or so of terraforming Mars, many bases and settlements have been set up. As an interim process to assist in terraforming animals and plants that can live on Mars have been created. These are hoped to assist with creating food and the development of an atmosphere. An eccentric bio-geneticist, Neals Wells, creates intelligent beings adapted to the Martian atmosphere. Creating intelligent life is illegal, so he flees with his creation into the Valles Marinaras, an immense Martian canyon where it has been found not practical to set up settlements. His creation propagates and, after a few centuries, develops into a small tribe.

Inevitably, the Martians come in contact with the humans who are terraforming the planet. This eventually leads to raids and war between the two species. Both species are similar but fighting for their survival. There can only be one winner in this contest, or can there?

This is the first part of the series' Mars is for Martians'. It spans several centuries of terraforming and conflicts between the human settlers and the Martians.
