I was prompted to read this by the references to it in "The Strange Case Of the Alchemist's Daughter".
I'm astonished: by how good the book is, by how different it is from any movie version I've seen, by how many stories can be nested in a single narrative and by the power of taking things slowly.
Most of all though, I'm astonished at just what an absolute tosser narcissistic fantasist Frankenstein is. I keep wanting to slap the man.
