I ran into this book on my phone and downloaded it, frankly, because it was fairly inexpensive and I was interested in learning a bit more about Taize. I have attended Taize events and our church uses Taize chants from time to time, so I was acquainted with those elements of the Taize story. I knew about the Taize community, but not really in detail. So, it was interesting to read more about the community; both its history and how it all works. Santos does give the sense of the place and that is valuable.
I think what disturbs me a bit, however, is the degree to which Santos dismisses the partial adoption of Taize songs and services. One gets the strong feeling that Santos thinks there really is only way to use these resources. I sympathize in the sense that I also think that one has to respect where practices come from, but I wonder if Santos gives enough scope for creative re-formulation in different contexts.
Still, this is an excellent introduction to Taize and is well worth reading on that basis.
