Hello. First of all, thank you for this wonderful plugin.
I seemed to have run in to a bit of a problem with it though.
I'm using Calibre version 0.8.54 and your Goodreads plugin. When I try to "Switch Goodreads editions" I get this message:

Spoiler:

calibre, version 0.8.54
ERROR: Unhandled exception: <b>TypeError</b>bject of type 'NoneType' has no len()

Traceback (most recent call last):
File "calibre_plugins.goodreads_sync.action", line 597, in switch_linked_edition
File "calibre_plugins.goodreads_sync.action", line 615, in switch_edition_for_linked_books
File "calibre_plugins.goodreads_sync.core", line 427, in get_goodreads_book_with_work_id
File "calibre_plugins.goodreads_sync.core", line 479, in _convert_review_xml_node_to_book
TypeError: object of type 'NoneType' has no len()

I have no idea what's up, it used to work perfectly so far.
Appreciate your help.
