Apocolypse (True story.... No jokes...)

Based on a true story. My names Chelsea. Im human, and im inlove with this guy, who I thought was human. But it turns out...he is a Nephilim (half fallen angel, half human). And apparently, this is the apocolypse. Throw in three teenage witches, a cocky fallen angel, two demon hunters, and self-righteous Demigod...yep, this is bound to be the beginning of an interesting end...
