Query: OK, but not great...

I did sort-of like it, but the bouncing back and forth between perspectives got to me this time. I didn't like many of the characters, and came very close to setting the book down. I pushed through, though, mainly to get to the next book in the hope that it would be better. The mystery plotline was ok, but not great - sort of anti-climactic, actually. Eh. Not one of James' better mysteries.
