Any new versions coming?

I'm working on redesigning our site and would love to use the BookPost module when it is in produciton. The problem I am running into is whenever Open Library is unavailable (Which has been often) I receive this error and my page fails to load.

Uncaught exception 'Exception' with message 'Open Library Data Unavailable'

Looking through several of the other issues I see where an updated version of this module hopes to cache this data so performance is improved. With the current version is there any way to have this module output a generic "Service is not available" message as opposed to producing an error that stops the page from loading?
