"Gospel" concerns the search for a lost first-century gospel of the Bible, a document that could shake the foundations of Christianity. Wilton Barnhardt's narrative races through three continents, nine countries, and dozens of colorful locales, as two characters - shy theological student Lucy Dantan and hard-drinking, disillusioned ex-Jesuit Patrick O'Hanrahan - pursue rumors and clues about the gospel's whereabouts and contents. In the end, what they discover will challenge and forever change the nature of faith.
