I struggled with giving this three or four stars. The writing, descriptions, and language are great (four stars), but to be honest I'm not really sure what happened at the end (three stars). I wasn't really sure who/what was Lydia and who/what was Kirstie, and it was never cleared up. Maybe that was intentional, but I didn't like the unresolved feelings about the "ghost," about the living child, and about Sarah. Great epilogue, though.
