I noticed this on my friend Jenna Goodman's list, and was intrigued. It is a Joseph Heller-esqe black comedy, and a lampoon of psychotherapy, at least as it is popularly imagined to be. The story is engaging, and some of the humor is clever... really the whole Satan angle is well done, but Satan isn't central to the story. The centerpiece of the story is the trial and tribulations of Dr.Kassler, J.S.P.S., who is a basically likable guy. The book only gets three stars because the trials he suffers cross from comic to meanspirited a bit too much, too often.
