On the positive side, I really want to visit Sark and see these places with my own eyes after reading this book.

On the not-so-positive side, this isn't very good, even though I kind of enjoy the overall story.

Without googling the answer, I suspect this was written long before Peake's masterful Gormenghast-trilogy, simply because so much of what made those books so good is lacking in this one.

I'm glad I read it, but I likely won't read it again.
