So, keeping in mind that Mrs. Eden isn't so comfortable with english, I have been searching for books on the subject of the historical Jesus and who wrote the Bible, and I got very frustrated because there's not a lot of those in my native language. Most of what I read in english simply hasn't been translated, which is a shame. In any case, I managed to get two: Bart Ehrman's "Misquoting Jesus" and Reza Aslan's "Zealot".
I've just finished reading "Zealot" in just one day. It's simple and easy to follow, at some points I find it a bit superficial. But seems to me a good introduction book for someone wanting to know more about the historical Jesus. It's useful to debunk the devotional reading of the gospels and the wrong notion that the NT displays a united church of the followers of Christ.
I recommend it, but as I said, it keeps things on a relatively accessible level, but for more in-depth research, there are better works. Have you read it?
