Souls are souls in the realm of Reapers. Life is life in the world of Angels. Business is business, even in the realm of Demons. And sex and love are terms that can confuse the hell out of a women.
This, in no means, relates to religion or is religious, so feel at ease. It is simply playing with terms and making what I wish with it, in this story there is no reference to god and/or you know the other dark being. Think about it as a different realm, with different rules ect, which is just what it is. Just like the other book "Engaged to a Fallen Angel," different realms don't think it's religious. Includes themes that maybe dark and a lot of adult content, don't read if you can't handle it.
