The fall of Earth

Daniel Ishikawa Park is just an average Martian boy. Raised on the farm and joined the Republic's galactic army at 17. However due to his unparalleled talents he and his squad become the best Mars has ever seen. So when all communications to and from Earth were lost they were naturally among the selected soldiers who would travel to Earth to investigate. Not knowing if it was freak accident or a terrorist attack, it is Daniel's job to find out and report back to the Republic.
