not sure if this is trustworthy
no sequel to Gentrified that I know of.
Hot Dates had 3 parts, a crossover with the ACHE Key Party event and a novella that bridged some of the time gap between the two. I highly recommend all of those.
Magic Hands is another I'd recommend. Part of book three, start of a later chapter, is like rocket fuel for me. It had a later Christmas-themed book that was pretty good too.
There's a new Key Party off-shoot that features a couple named Gray and Nicole. Don't know if they're from any existing book.
I believe Carol's Trinity is the author's favorite.
