Indexing: Reflections (Indexing Series) - Seanan McGuire
While Jeff and Sloane were fretting in the last chapter, this is what Henry was going through -- and pretty soon you start to think that maybe Jeff and Sloane were better off (as worried as they were). But honestly, there really wasn't a lot of plot movement here. It's primarily a chapter that expands what the reader knows about the story. We get a better understanding of how things work in the whiteout wood that the Snow Whites like Henry in habit, we get a little backstory on Henry and Gerry, and the beginnings of an understanding what's going on with Elsie. 
Which isn't just to say is all exposition, or dull -- because it's not.  But the fight scenes, the danger, the tension takes are of secondary importance.  It's a good chapter, and does a good job of establishing a foundation for whatever is going to come next.
The ending could be cliff-hanger-y.  But didn't really feel that way, it felt more like one more hurdle for Henry to conquer.  It seems like a pretty big hurdle and one not easily overcome.  But I, for one, am not that worried about the outcome. 
Of course, with my track record of predicting McGuire means I should probably  be sweating bullets.
