Most Immortals (and all of the ones featured in the novel) believe in a Higher Power. Most refer to that Higher Power as God, but the Immortals accept any name given to that being (God, Allah, the Creator, etc). To them, all of those names refer to the same being. Immortals are not as stringent as humans when it comes to religious beliefs; they feel that every culture is entitled to their set of beliefs and celebrate the similarities between major religions rather than the differences.
The Higher Power belief is very strong in the Immortal world, but I chose not to go too much deeper into their spirituality with the fear that it would take away from the Forbidden Children plot (and later the Tylea's Blood plot, which is the working title for book two). And yes, the vampires and werewolves believe in a Higher Power as well.
This, of course, brings up the ever touchy subject of religion in fictional works. Heads of different religions appear to be wary of the questioning or altering of their beliefs, even in a work of fiction. Look no further than some of Dan Brown's novels and the reaction of the Catholic Church to see an example. I believe that many writers don't go in trying to attack a particular religion (although some do); we go in to write a compelling story, and religion is one way to make a story compelling.
Rest assured that even though religion does pop up often in Forbidden Children, I am not trying to attack or dismiss a religion. I am introducing you to a world different from your own, beliefs different from your own, and a general world view that is different from your own.
