Power of the Zega

What happens when America falls to a war with a distant country, and almost everyone flees? Wolves take over their cities!
Crescent is a wolf living in the outskirts of a broken city ruled by an evil Alpha. When a blue wolf in the lowest, newest position- a Zega- is prophesied to lead a war against Alexian's growing rule of shadows, she can't help but wonder if the symbol on her head means something, and if it is at all related to the prophecy.
Then, one day, Alexian grows tired of the blue wolf's presence, and she is thrown out of the outskirts, forced to survive with nothing but her instincts, and her two closest friends. Can she live to save her mother, and the ruins of the last free world?
Or is she doomed to fail?
