Born Fallen

Kasadaiya is what the supernatural world calls a Fallen. A rare breed of supernatural with unknown potential, though no one cares enough to actually learn what they can do, if they can do anything at all.
Being one of the best graduates of all time from the Acadia Academy for Angelbloods, she is a very dangerous asset. Especially now, during a time at war with an Angelblood gone bad.
While at war with said big, bad wolf, Kas, along with her partner-in-crime, is sent to secure and protect one of the more elite academies. There she meets an Angelblood Prince, which, in her experience is just another way to spell prick. He is strong, fierce, and her partner in her advanced combat class. He also hates her, for a reason that Kas has yet to determine.
Zarco has plans to take over the world, one species at a time, starting with his own: Angelbloods and their counterparts the Demonbloods. Using his species, he is able to begin conquering other species, with little chance for anyone standing in his way. All that is left of his species is two packs, and two just isn't a match for the hundreds that are already in compliance.
With Zarco's army growing at a rapid pace, making him ready to blow the already teeter-tottering world into chaos, and strike down all those who oppose him, Kas has a lot resting on her shoulders. Being the only one with the tools and information capable of stopping him, there is a lot at stake if she can't get her now-permanent partner to work with her. Him being the last Alpha not under Zarco's thumb, she kind of needs his help.
Can she be the hero that the world needs in order to be saved, or will she fail, and end up destroying everything?
