Reader Expectation, The Suzanne Brockmann Edition
JMC has a great post up regarding reader expectation. Apparently there is some question as to whether a couple of characters who have been together over the course of several books are being torn apart and given an HEA with a different couple. Brockmann is notorious for having what she terms unreliable narrators wherein the POV told by a character may actually not be accurate but you don't find this out until several books down the road. This appears to be the case, although JMC argues that the signs, if a reader was looking for them, were there for the reader to spot the inconsistencies in the narrator's POV.
