This is a breakthrough book written on an important subject to children, parents, and grandparents. The subject is Dementia, or what is commonly referred to as memory loss. To the best of my knowledge, no other book on this subject has been written specifically for children ages 9 to 12. However, Hudson's and Charlotte's endearing adventure is for all readers; children, parents and grandparents. Your children will relate to the adventures of these two young girls, and as they learn about memory loss, so too will you and your children. As people live longer, the population winding up with Dementia is rapidly growing. Parents find themselves ill-equipped to talk to their children about this subject. They themselves know little, and without basic mental health knowledge, parents are unable to discuss this issue with their children. If you have a parent that is fine today, they could start the long, slow, goodbye tomorrow. I believe this book is a must read for all ages, and parents in particular should read it and discuss it with their children. Because this is such an important issue, I am going to donate 10% of my royalties to the Alzheimer Foundation.
