I bought this book in the Portland airport just before a flight back home. Usually I pick up a book for reading on a flight, and when done leave it for either the airline people or another passenger to pick it up -- but not this one. I was hooked from page one and when finished I kept it and loaned it out to others as a highly suggested read.
This was my first Emerson novel; what is interesting is how it shows that he (the author) had developed his ability to paint characters richly as well as handle plots with more dexterity than in his earlier novels, which I sought out to read after this one. I also have read books he's written since this one (except his latest, "Catfish Cafe"), and feel this is his best effort -- both in the Thomas Black series (this book features Thomas Black) and in the Mac Fontana series.
If you are an Emerson fan and haven't read this one, by all means read it. If you've not read any Emerson books yet, make this your first one. I don't think you'll be disappointed.
