Spartans Rise

The human race was about to make a quantum leap forward in technology and bioengineering when they were attacked and almost completely wiped out. Now after 400 years all that is left are a few large fortified cities on Earth and an elite military organization led by Hannibal that keep the marauding aliens at bay. Now with an ally the humans are beginning to win back their world. Marcus, Leo his brother and Patrick their father are escorting a caravan between cities when it is attacked. They help defeat the aliens and they become key players in advancing toward the human race's former heights. Marcus in particular opens doors that no one even knew existed.
