SPOILERS AHOY
Oh, how deliciously, distressingly complicated it all is! Not at all a True Romance--I can see how Iacob systematically broke Hermione down and recreated her as the woman of his dreams (with some key help from Alfie). The characterizations are spot-on; at first, I didn't understand why Hermione would at all acquiesce, but by the end, I was as convinced as she was.
I still feel discomfited by the end, but truly it's what would be best for Hermione. Probably.
