What is I Sold My Soul on eBay?

I Sold My Soul on eBay: Viewing Faith Through an Atheist's Eyes is a non-fiction book by Hemant Mehta, an atheist and blogger, and podcaster, who describes his visits to a variety of Christian churches. These visits initially occurred as a result of an eBay auction Mehta created where he offered to visit the worship services of the winning bidder's choosing. The media later branded this auction as Mehta "selling his soul."
