The Mighty First, Episode 1 - The Mighty First series, #1

Our world plunged into chaos. They came from the galactic center, attacking us unprovoked, laying our infrastructure to waste in the process of occupying Earth. Young Minerva Carreno felt compelled to answer the call to service, leaving high school to enlist in the Global Marines.  Basic training would try her soul, but assignment to the battalions still lay ahead.  Follow Minerva and her cadre of the 1st Combat Division in the desperate fight to liberate our world one city at a time in this futuristic drama told with a WWII vibe that is sure to please all ages.
Told in 1st-person narrative, Minerva describes her transition from timid small-town girl to the hardened veteran that the Corps transformed her into, followed by the harrowing engagements her unit encounters in what is essentially a futuristic version of World War 2 on a galactic scale.   Thrust into a leadership position she does not feel ready to accept, Minerva struggles with her own confidence, and the heart-breaking consequences of sending her closest friends into battle.
