This is such a glorious story! Augusta is wonderful in her outspokenness, and Minerva is a match for her in every sense of the word. Love Gussie's ideas on wine (very proper ideas, too) and Minerva's dislike of vermin she wouldn't eat in cat-shape.
The way you weave every meeting into canon, and the scorching-hot sex made this one of the delights of this year's fest for me!
