I also really enjoyed Baker's ability to tell the truth without worrying about letting the chips fall where they may. Proper society is one that we might predict from watching current popular sociological trends. Although the "Goddess" worship popular among Mary and her cronies is linked to the Virgin of Guadalupe, it is also a nebulous sort of faith which encompasses something far beyond any Christian understanding of the Virgin Mary. And yet Baker isn't afraid to include Christians among those who would be thrown into the Hospital for Eccentrics, which is something a good many authors would have been blind to, depending upon their own prejudices.
This book is set in the world of Baker's series about "The Company." It is a stand-alone and only tangentially connected to that series. I honestly didn't recognize the two obvious Company characters who were included (Mr. De Wit and Mr. Nennius) but knowing who they are explains why they are enemies from the time they meet.
Overall a fun, light, imaginative read.
