Seven Sisters Series

Seven Sisters: a seven book series set during the end times of the world of Atlas. The sisters and their clan race to save the people of their world as the last archipelago loses island after island to the rising ocean.

Atlas was once a world of ice. Terraformers believed they could make an idyllic world and began with a haste that did not include feasibility studies, or any meaningful analysis. Humans and Lizard People began to settle on the world, until the Lizard People realized that there was enough ice still left to more than flood even the tallest peaks. Most of them deserted the world, sending their tidings of flooding to the inhabited planets.

Settlement stopped. Soon it was not worth making the trip to Atlas. The planetary engineers abandoned their project, leaving the remaining settlers to their slowly melting ice world.
