Menedék Stories

Note: I will post at least 2-3 chapters a week. This is not the complete book. This is the first book in the Caitríona's Sky series. Any advice would be much appreciated. It's the year 2914. 17 year old Caitríona lives on planet Menedék. After learning the truth about her mother's death, she is sent to the ruins of their previous home, Earth. Will Caitríona save humanity? Or will she herself die in the process?
