Books for a soon-to-be-widow?

My father-in-law has terminal cancer. He’s doing okay health wise at the moment, but is rapid declining, and we’ve been told to prepare for this to be his last Christmas. We have plenty of gifts and plans for him, but I’m looking for book recommendations for my mother-in-law. Something that would offer support, guidance, etc. something along those lines. Open to any recommendations
