Sara is actually a friend of mine and pretty well known around scifi cons and the like. AY&AD is about the Angel of Vengeance and the Angel of Joy spending a year and a day in NYC in human form. Joy is there to complete an assignment and Vengeance is there as her chaperone. Sara's writing style sucks you in. I found myself getting emotional at parts as if it were happening in real life. I also found myself having emotion (good and bad) for characters as if they were real people.

A collection of speeches and stories in the LGBTQ movement. Not as good as her other stuff, but good nonetheless. Kind of dragged in some parts.
