After nearly a year of destruction and the decimation of populations, the Earth stood on the brink of an apocalypse. Extinction was a very real possibility for the mortal and immortal species that stood together facing a threat that had plagued them for generations. Seraphim came to everyone on wings of grace, as saviors, sent to protect all people from the menace-- their blood gave way to a vaccine so that no one else would have to suffer that loss. So forth came these angels, almost from a bible verse, followed by shady counterparts who claim to desire to aid the people in life...though they resemble nothing more than deceptive serpents, who are the people of Earth to question such gifts when new paths have opened to all because of them? And don't forget to ask how soulmates have begun tying into this world... The bonding gene in Seraphim blood opened a gateway. Just a single kiss could serve to remedy severed pieces of your soul, revealing who you belong with, forever.
