Although in "Liar," by the end of the book there seems to be a distinct possibility that Micah is at least intermittently insane, instead of (or as well as) suffering from the particular "illness" to which she ultimately attributes most of the teen-angst-bullshit-with-a-body-count that she's been involved in one way or another. So the fantasy element that supposedly explains much of what happens (in different ways depending on the different ways she retells it) may be just a delusion on her part, which could make this story somewhat problematical for Sirens purposes.
