The long answer is :
The idea of a lost soul wading his way through an infernal Hell, and an angel--the love of his life--saving his soul all they way from Paradise. I loved the idea and I loved the books!
C.S. Lewis has also been a huge inspiration. As as child "The Chronicles of Narnia" transported me to...well... Narnia! As an adult, "The Screwtape Letters", with humor and sarcasm, made me think about what the enemy of our souls hopes to achieve.
There have also been other authors who in different ways have inspired me. Victor Hugo, Tomas Hardy, Charles Dickens, and many, many more.
But I do have to say, that the scirptures have inspired me the me the most. Nothing sends my mind into a speculative spin like a good verse from Revelations! When I die, I would love to sit with him and chat. Isaiah too!
As you read my books you'll notice that I've spent quite a lot of time speculating about Cherubim, Seraphim, Legion, and the infamous "whore that sitteth upon many waters" Rev. 17:1
Ha, Ha! I laugh, but I don't mean any disrespect. I just read this and I think,"what did John The Revelator see? Who was she? What was she?"
For this reason I request an audience when I cross over. Hope the line isn't long.
And if you are wondering what I did with this verse, and how I incorporated it into my last book "Endless", you'll just have to wait until this coming December 2013!
