This it the 2nd book in the Demon the Fallen Trilogy, based on White Wolf's World of Darkness role-playing game Demon the Fallen.

This trilogy was written for the game created by White Wolf for the World of Darkness, and I think this was one of the best series for any of their games.

We met several demon possessed people in the 1st installment of this trilogy and this is a continuation.

The demons ARE the person on the inside though some of the possessee' might have some small influence on their 'captor'. To possess a body the host needs to be dieing, almost dead, or willingly give it up. Here we continue with the apocalypse already in progress and Satan has been seen running around LA. Demons are breaking out of hell in record numbers. Things are starting to get VERY interesting. ( )
