I've been working on revising the first volume of the Praying the Mass series. The second edition of The Prayers of the People is due out by the end of the week (assuming the proof copy I receive is up to par). A dozen pages of additional content, but the same price of $12.
I have finished copying the new content to the book's web site. If you have the first edition (or if you just want to know what's new in the book), you can read all thirteen blocks of new content here.
