I recently read Misquoting Jesus by Bart Ehrman. It was very well written. I think the title perhaps written by the publisher, a misnomer, but a good marketing ploy. In the introduction Dr. Ehrman explains that the book is somewhat of a textual-criticism for lay readers. Textual-criticism he explains has long been the concern of very specialized scriptural scholars but the average person doesn't understand the archaeological scriptural discoveries that have recently been made.
