This would work much better as an e-book with links to the pictures. Although it's quite lavishly illustrated, the text discusses a lot of pictures which are not included. I'm going to take it slowly and look at the artists online as well.

Judging from what I've read so far (about half way through the second chapter), she's going to stick to the West European tradition, Catholic and then also Protestant. Haven't other Christian traditions produced any art?

I can't comment on her knowledge of art history but her knowledge of general history seems a bit shaky. Unless it's because of very careless phrasing, she seems to be saying that Henry VIII's dissolution of the monasteries came before Luther's reformation. There were some other things she said earlier in the book which struck me as odd, but I can't remember what they were now.

Another problem that is becoming apparent is the lack of any real definition of what the author means by 'Christian' art? Is it any art painted by Christians, or is art on biblical or other specifically Christian themes? For example, she takes as one of her examples from the work of Peter Breugel the Elder his "Haymaking". It's a nice picture, but what's particularly Christian about it? ( )
