A most excellent wrap-up to what's been a fun ride. I admit to definitely looking forward to your next work.
Heh, I thought the end for Albus was quite appropriate, he survives but his reputation and agenda are in tatters and can't be regained. Meanwhile, i found the end for Rita to be particularly appropriate and fitting. That the magical and mundane societies merged is almost a necessity as the shrinking population of the magical one and the increasing abilities of the mundane one (multi-spectral sensors are going to make it much, much more difficult to hide the magical world) are going to force it; at least the technomages here are in a position to build bridges and ease the merging. Finally, I rather suspect that Harry was chuckling all the while as both of his wives become more famous than him.
