Bart D. Ehrman has written a lot of interesting books on Christianity (some of his work might be considered controversial to some practitioners). E.g., "Jesus Before the Gospels: How the Earliest Christians Remembered, Changed, and Invented Their Stories of the Savior" "Forgery and Counterforgery: The Use of Literary Deceit in Early Christian Polemics" "Lost Christianities: The Battles for Scripture and the Faiths We Never Knew" And, many more. I don't know of a commercial book site where I can just link to a search by author: https://libgen.rs/search.php?req=Bart+D.+Ehrman&lg_topic=lib...
