Yes, I must agree re: the potter. Left quite a bad taste in my mouth. As a mystery, too, I thought the pacing was not helped by stretching it over two books with different protagonists -- despite being part of the whole climax, the Evil Heads plot felt like it got slightly short shrift in the front two-thirds of the book, and so the switch over to the A mystery plot from the first book in the back third felt a bit jarring/unearned.

I find all "lust at first sight" vaguely perplexing, but, you know, I do think Breasts are Magnificent, so I feel like I can excuse it a little :p
