3.5 stars.
I learned quite a lot about the reform of the liturgy during Vatican II, and in impressive detail. It was also entertaining to read.
However, some of the author's rants or subtle implications against more traditional Catholics, even ones who simply don't wish to receive the Eucharist from a female layperson - "The absence of the Eucharistic prayer did not make much of an impression, as long as people got communion! There was a hue and cry about suppressing communion services, largely because laypeople... including women... were leading them, but at the same time an opportunity was missed" (105) - were sometimes annoying, sometimes downright objectionable, and sometimes a little catty.
With all that being said, this is still a good resource - particularly if you want to learn just how much the Mass changed after Vatican II!
