The Price of Revisionist History

I've begun revising The Price of Entanglement, which is not proving to be easy going. When last I touched it, I was having some serious issues with the direction I'd been taking it in. These revisions I'm doing have resulted in backtracking several chapters. I've basically consigned everything from chapters 11-13 to the garbage bin, and I'm continuing on from chapter 10 forward. That was the last point at which I felt the story was pretty strongly on track.
