on the major Shabbat home prayers, especially the Kiddushes and Havdalah. The commentaries are from a variety of perspectives, both ideological (Reform, Orthodox, and Conservative) and subject matter (Tanach, feminist, halachic, theological, historical, etc.). I found the halachic commentary to be the most interesting, since it is of the most practical value for anyone seeking to observe Shabbat.
One thing I would have changed: the 30 pages spent on Shabbat table songs. Because different families use such a wide variety of songs, any attempt to focus on three or four of them is likely to miss a lot of songs used by lots of people, and to use a lot of songs that lots of people have never heard of. I would have preferred to see the extra space spent on Birkat Hamazon (the blessing after meals) since that prayer is almost universally said after Shabbat meals.
