Query: This is the one to buy

I bought several books of this type and this one is by far the most helpful and informative. It was invaluable in my visits to assisted living and nursing home facilities - letting me know what to look for and what questions to ask. But there is so much more to this book than just that. If I could only buy one book to help me understand how I can help my parents this would definitely be it.
