My GF and I are planning a week in Oaxaca from just before Christmas to New Year's Eve or so. We have Mexico guidebooks with a few pages on Oaxaca, Monte Albán, etc., but that's all. Anyone have any suggestions for something more in-depth?

As one possibility, we just came across a pointer to Viva Oaxaca by Adler and Wexler on the Web. Has anyone seen the actual book? Any opinions one way or the other? (If nothing else, we won't risk much money by getting a copy.)

Any and all suggestions for things to do while there would be gratefully appreciated as well, of course.
