This is one of my favorite series, but after reading the reviews I opened it with some trepidation.
I think that it is as good as always: the complex plot, the dry humor, the mixed feelings of the characters. The characters are, as usual, well-developed. I hope that some of these characters will at least be featured as minor characters in future books. Characters who reappear, even if only intermittently, add to the fullness and reality of the author's universe. I kept promising myself to put it down at the end of the chapter, and ended up reading it through.
One of the things that I like about this book is that it does deal with people and their work, one of the most ignored themes in literature, except for artists and detectives. In this book, the characters discuss the realities of running one's own business. I was very amused in an earlier book when Betsy went from being a tenant complaining about the poor maintenance by a greedy landlord to being the landlord who had to pay for repairs. The people also have a relatively realistic view of money: they like having it, even if they wouldn't necessarily do almost anything to get it. I get very tired of books about wealthy people of leisure, or at least an oddly undemanding job, with an apparently inexhaustible private income.
In this book, except for Betsy and Godwin, the regular cast of characters make only cameo appearances. In itself, I don't find this a problem, although of course I want to see the regulars again, I thoroughly enjoyed these characters. I am a trifle disappointed that there wasn't a book between this one and the last with a subplot centering on Jill and her new baby, but I don't consider it to be a flaw of this book, per se.
The reviews make it clear that the gang is not all here; readers can choose for themselves.
