I had read Heaven Help Us! many years ago and greatly enjoyed it, so when I saw So Help Me God! at a used book sale I immediately bought it but then didn't read it for a long time.
The blurb is somewhat misleading because Andrew is the main character and narrates the story in first-person. His friend Levi isn't present for most of it. Andrew's father is Jewish but his mother is not, so by Jewish law Andrew is a gentile. Despite this, he enrolls in a rabbinical school in an attempt to avoid the draft during the Vietnam war. I'm not sure whether my lack of enthusiasm while reading (in comparison with the author's other book) is because of how the story is dated or because of how I've changed.
