When I first watched a scientific video about tardigrades and heard their capabilities to survive in the harshest environment, I guessed they were the best choice to place them on other planets. Thinking about using this macro- animal to prepare liveable conditions for other creatures, persuaded me to write this science- fiction book. At first I wrote it for a science- fiction movie but noticed it was difficult to persuade an interested film studio or producer. I began working on HARDIGUARDS and the HOLY MOUNTAIN since 2016 and was able to copyright it on March 20, 2018. After that, the book went through multiple editorial processes and revisions to get to this point. I used many scientific facts and let my imagination travel far to create a story that is exciting, challenging, and educational. I also tried to apply tangible elements that are relevant in the world today, which allows the reader to be a part of the story. I wrote this first series in a classic Si-Fi version, devoting more time to the foundation for the next parts.
