What if Jesus had a half-sister? Well, now he does; her name is Julie Katz, and she was born in Atlantic City. Lacking strong daughter-of-God role models, she is more than a little uncertain what to do with her life. (The author takes this opportunity to discuss at some length the significance of an individual's efforts to change the world.) So she tries tabloid journalism and takes a sojourn in hell, to start with.

The book is well-written, often laugh-out-loud funny (for some values of "sense of humor"), though it spans a long time and can be telegraphic. The Relevationist leader is disappointing, but most of the major characters are better.

I don't know about the ending. Maybe I was distracted by the toxicological shenanigans (which you may not notice if you don't follow that link), but I was more concerned with the use they were put to. I didn't think it was necessary. In fact, it seemed thematically incongruous, as did the other deus ex machina occurrence near the end. The author probably disagrees.
