Geography of Memory
I ordered this immediately after hearing the author speak last April, and spent the next six months staring at it on my bookshelf, afraid to begin. I worried it would be really depressing, but the preface put my mind at ease. (The first line: "I wrote this book because I believe the news about Alzheimer's is more hopeful than what we hear on the street.")
A book about Alzheimer's, but also about mothers and daughters, understanding your past, and the power of memory. Poignant and powerful.
