The Everborn

The Everborn concerns the offspring of fallen angels that have lived among us since the dawn of man. Throughout the ages, they live life after life in normal society until each one falls in love and fathers his own child. Before that child is born, they undergo a rapid degeneration into a fetal state before they disappear entirely and become reborn into a new life, essentially becoming their own fathers.
All of them male, they live out their commonplace lives under the covert protection of Watchmaids, inter-dimensional female beings whose purpose is to ensure no harm comes to them under penalty of banishment into a state of eternal loneliness. When an Everborn is reborn as a set of twins, one a soulless serial killer on a quest to be born again into a sinless life and the other a kind-hearted ghostwriter for a world-famous rock-and-roll horror novelist, a banished Watchmaid claims her role in an ancient prophecy to use the soulless twin as a means to re-enter our world and bring about its destruction.
