Through The Iron Gates Of Life

We are the in between
cast down as sons of war.
Struck to the Earth like lightening
on this world we're torn.
We won't cause the pain,
of living out their law.
Take joy in who you are,
we know our wings are flawed.
We're bored to death in heaven
and all alone in hell.
WE ONLY WANT TO BE OURSELVES

Quick summary:
Azriel is an angel, who committed a sin that he himself does not know of. Yet even without evidence, he is banished from heaven by the will of God. He finds himself on Earth where he is rescued by a woman, who seems to resemble the same person his father tortured to death.
