I do find the Something Something books to each be better than the last; in part because they give Hall a chance to showcase his impressive talent for taking "that bleeping guy" from the previous book and making them a fully fleshed out and deeply sympathetic main character.
Also I appreciate that, in doing so, Hall does not force them to come to terms with the character who--having read about before as deeply sympathetic, you now like a little more. 
Also I deeply dislike Bonny and his near absence in this book was appreciated.
I love that Hall is interested in what a queerplatonic relationship looks like, I love his irrepressible tendency to make fun of absurd things by putting them in the wrong century, and I really love that Hall understands that romance novels are at their best when they are asking "how am I to be good?" Because this is a deeply ridiculous story that is all about the question "how am I to be good? And to myself, most of all?"
