I imagine she'll probably manage to make a bunch of folks angry at her for her interpretations, get all kinds of publicity, and sell millions of copies. People will try to make it the new century's "Last Temptation of Christ", soley on her reputation and the things she's written in the past ("She can't write about Christ; she's written pornography!" - I can hear it now), whether or not she's written anything offensive.
Personally, it has always interested me that there is no information about that part of Jesus' life. Whether you are a believer in Jesus as a deity or are just interested in the question of whether he was or was not an historical personage, I would think that this would be a fertile area for exploration in fiction.
