Mad Viking,
Part of the problem with the Book of Abraham is that there are many scrolls and documents associated with it, produced by many scribes. I think the Book of Abraham is a
pretty simple KO, but to have a full understanding of the issues takes a little work. This is especially true since the apologists have worked so hard to sow confusion.
An excellent place to start is
By His Own Hand Upon Papyrus by Charles Larson. Alternatively, roughly the same material is covered in Kevin Mathie's
online book,
Examining the Book of Abraham. Another great book on the subject is H. Donl Peterson's
Story of the Book of Abraham. Peterson avoids the controversial stuff, but gives lots of helpful historical information. I also enjoyed the Tanners' chapter on the Book of Abraham in
Mormonism: Shadow or Reality? Larson basically plagiarized the Tanners' work. And while he made it more accessible, quite a bit gets lost in translation. The Tanners had a way of exposing apologists' folly that makes for fun reading.
Best,
