Has anyone read Mary Rubio's new L.M. Montgomery biography called "The Gift of Wings"? As you may recall, she was one of the editors of LMM's journals; she also did quite a bit of primary research, such as talking with friends and family of LMM, which led to this new biography -- and some surprising facts, including, for example, the truth about Chester's life, the things he did, etc. She also talks about LMM's death.
If you haven't read the book, I'd really recommend it. It was really interesting for me to read the other side of the story regarding all the major events in her life.
