The now familiar characters dive into spring as only they can - not exactly enthusiastically, but with a sense of fatality and good humor - except when the good humor escapes them. They are, by now, so well defined that the reactions of the main characters can almost be predicted.
Except when they are faced with situate no one can prepare for, like the sky apparently falling, or a gunfight at the Okay Corral.
They do their best, they solve the problems, and prepare for the next go round.
Well worth the read.
