Have to say, the way this was building up I was expecting a finale. The last half-dozen pages, however...
I am looking very much forward to the fifth book.
The art was beautifully done, particularly (I thought) the Sparrow
opening issue with the Calvin-and-Hobbes style, and the slice-of-a-day treament of February
. I think February did a lot to round out the cast beyond Kinsey, Bode, Tyler, and Dodge, too; not that it particularly focussed on other people, but it did flesh out the core cast's relationship with others, and that helps.
On that note, I was very glad to see more of Rufus. Kind of missing Mrs. Locke, though; she was around for two pages, and they were really mroe scene-setting than plot.
Going to reread the other three before offering more in-depth commentary, I think.
