5-star confirmed on the re-read! I'll even stand by my surprising original assessment of "perfectly paced" but I'm sure that pace drives some readers mad since most of the "action" happens in the last 20% of the book.

I did not know if I would even like this and certainly did not expect to love it, but wow — 4.5 stars, unhesitatingly rounded up to 5. Quietly powerful, surprisingly cheerful, on the sweet side of bittersweet, intriguing, charming, philosophical, witty, beautifully written and perfectly paced...
