This is a novel about the collapse of civilization due to an oil crisis with a twist. Somehow a bacteria called Tar Baby is released into the environment and systematically destroys the world's oil supply by causing it to bind up to the point of being tar-like. Since we are so dependent upon it the world quickly spirals into chaos and the population dies out in dramatic fashion. What survivors remain must deal with dwindling supplies, very corrupt government officials (what remains of the internet is under total government control and law enforcement is often on-the-take). Carlos is a man with a secret - a secret that a witch wants and kills him in an attempt to procure. His son whom he placed up for adoption after his wife's death comes to Purgatory to claim his inheritance and his father's problems. His father's enemies lie in wait for him to discover what they want so they can steal it for themselves and not only must he protect himself but his father's ward, a young woman named Jennifer who has lived on his father's property most of her life.
I found this novel to be interesting but not the type of novel that I can't wait to get back to. It has interesting ideas and is ambitious. I give it 3 out of 5 stars.
