"Me of Little Faith" by Lewis Black
One-paragraph review: Lewis Black has a severely complicated relationship with the metaphysical. He has deep opposition to organized religion and rejects a lot of other people's interpretations of things like faith and the mystical world, but he seems to have a profoundly difficult time shaking the notion that he thinks something should exist in the void. Unsurprisingly, his audiobook is narrated with his characteristic disgruntled-man voice and a lot of expletives (which aren't bleeped). The audiobook concludes with a largely unnecessary sketch that drags on and detracts from the main theme.
Verdict: Interesting enough company to keep for listening in the car, provided you aren't offended easily by someone dismissing faith and don't hav any children in the vehicle with you.
