Let me say this upfront: This is not the kind of book I normally read. On the Edge is full of sex, greed, destruction, lies, and more sex. Yet... author F. Parker Hudson's tale is woven so well that I was able to mostly keep the squirming to a minimum. The power of the book is its revealed spiritual truths. Angels and demons go after a family in deep trouble. It will offend many, surprise others, and cause many to debate its theology (me included). But I couldn't put the book down- and it placed my prayer life on fire in a whole new way. Check it out- if you can stand it.
