This novella comes after book 3 and is the end of the series as far as I know (I can think of one other couple who could get a book) and some people might have been annoyed by potential spoilers since the whole crew is there in the end, I didn't mind. It was mostly still about Alex, River, and Mia and happens between the end of their book and it's epilogue, and is mostly spicy with a little plot. Something at the end of this one might not have been mentioned in that last epilogue, which doesn't make sense, but I'm not sure if it was something that was skirted around on purpose, a continuity error, or something I don't know from the earlier two books (maybe the book about that couple has an epilogue after this one even and explains it).Regardless, this was fun.
