I enjoyed this story.
I have a comment to other readers. Why do some readers feel the need to correct what they view as spelling/grammatical errors in a book - IN INK? Apparently, one reader of the copy of the book I read even took issue with wishing someone a 'Happy Christmas'. This reader crossed out Happy and wrote Merry.
If you own a book, it's fine to write all over it but these aren't your books and I think it's very rude to mark them up.
