There is so much about this book that is just excellent, until you get to the last 20 pages or so. I was disappointed in the ending, which surprised me. The book within the book, the fictional memoir of a real artist, Elisabeth Vigee LeBrun, was interesting and moving. The outer story was very evocative, with interesting characters and thoughtful tropes on aging. But still trying to puzzle out how it could have felt so unfinished.
