Just to carry on the trend...In the same 'World of Darkness.' I offer up....
Thomas Sniegoski's
A Kiss Before The Apocalypse.
Another private eye themed book, with heavy religious overtones. The main character is Remy Chandler...Formerly known as the angel Remiel of the Heavenly Host Seraphim. Set in the modern day, it frequently flashes back to Remy's history. (Read: the war in Heaven, the fall of the Morningstar, and Remiel's decision to leave Heaven behind)
It starts out with Remy working a typical adultery case, having tailed the target to a motel. Whilst waiting outside, he hears a gunshot. When he goes to investigate, he finds the mistress naked on the bed with a bible clutched to her breast and a fatal bullet wound. The target, whom is also naked...and holding a gun, claims to be able to see who Remy really is, and can't believe that one has been sent for him, then kills himself. Later in the book, Remy's called to the hospital...The couple aren't dead...But their souls are screaming out in torment, wishing to be collected, along with many others. The Angel of Death has gone AWOL, and has taken his scroll to summon the Four Horsemen of the Apocalypse.
I've also read his short story that appears in the anthology Mean Streets, featuring Remy.
Couple of interesting notes from the books...
A lot of Angels don't like Mankind...Apparently we're God's favourite pets, and have a unique spark of the divine in us that even the Angels lack.
Many of the fallen Angels have really messed up ideas about how to get back into God's good graces, including slaughtering their own children.
Again, nothing really mind alters, or view of the world changing, but a good read IMO.
