This book was so good. I'm not sure what the specific feeling is that this book evokes in me, but it's one that I love in books. An angel and a demon working together to do a mitzvah across the sea, learning so much about themselves and others. Add in irrepressible Rose and tenements and factory strikes, and it's a winning combination.  I think the one thing I wish had happened was that I knew there was a glossary at the end when I started reading. I would have appreciated knowing that earlier in the book.
