I'm definitely in the minority/minority here, but until the last quarter of the book, I found pretty much everything about this book annoying. The story is ostensibly about the difficulties of taking care of a parent who has early onset dementia compounded by the complicated relationship that preceded the onset of the disease. The segments related to the care were often poignant. However, whether intended or not, the book (in my view) was written from the perspective of, "Look at all the terrible things that happened to me!"
At various points, the author (who was a married adult at the beginning of the book) seems to make it clear that she believed her mother owed her a certain way to be that would carry on into perpetuity. Even before she knew that her mother had early onset dementia, she complained that her mother (who even then obviously had something wrong with her) didn't tend to her needs by immediately coming from the east coast to the west coast to help her with her newborn. The daughter never thought to investigate why this refusal (anomalous in her view) was occurring, but rather just complained about it for a third of the book, even blaming her mother for her own mental difficulties.
Even before the reader makes the discovery that the mom has a physical issue, I found it odd that the daughter would even ask her mother to take leave from her job and come take care of her child in Seattle. The mom, after all, was nearing retirement age and probably not in any condition to be the caretaker of a newborn. Nonetheless, there is no indication that the author took any interest in what was happening with mom, or, in any way, thought she should be responsible for making her mom's life easier or better (regardless of whether mom was sick or not).
I expected a shift when it was made known that Mom had dementia, but the author pretty much remained angry that she wasn't getting the mom she wanted to have. (Apparently the mom who "fixed" everything and was more self-sufficient.) This anger was only partially aimed at the disease; it was often aimed at mom as the author tried to reason with a person who wasn't fully capable of reasoning. There was only a limited acknowledgment of any revelation that, "Wow, I really need to shift how I'm looking at this. It's my turn to be the caretaker now." Even if that occurred, it would soon go back to frustration and anger that the author couldn't make mom the person that she wanted her to be.... And that spiraled into delving into how mom maybe hadn't been so great a mom anyway and how that had also screwed up the author's life.
One of the things that the author either didn't get or didn't convey was that even the most dedicated and altruistic parents can't save the day into perpetuity. Even those parents who don't get to the stage of being elderly do get older and less capable. Even before the author's mom was known to be sick, I thought the author had a pretty high expectation about what the mom should be doing as a parent. There really didn't seem to be a part of the book (at least for me) where the author looked at her mom as an individual human being as opposed to the person appointed to a particular role in the author's life. I did see some sympathy, but not a lot of empathy, and always through the lens of how everything affected the author, not what the mom was going through and why.
I have had an extensive amount of experience with elder care, especially with difficult elders. I also had parents who weren't always quite what I hoped they might be or what I needed them to be. I think I was sufficiently angry in my twenties and perhaps thirties and probably did have unrealistic expectations of them. However, when your parents get to a certain age, you come to realize that you're not going to be able to rehab them into people who care about things that are important to you (or validate the "you" you want validated) if that's not who they've ever been. They're also going to stop being the people who can jump in to save the day in situations they may have "fixed" previously.
It's pretty trendy now to write memoirs about how our parents wrecked our lives. For a variety of reasons, many of them did -- some purposely; some because they couldn't change things or didn't know any better because of the times they grew up in. Despite our best efforts, we will likely do the same to our own children for one reason or another. I understand that some people's parents were really terrible and it is difficult to ever put aside that trauma, but that really wasn't true of the author. Although I certainly wouldn't expect anyone to be immune from the frustration of dealing with a person who has Alzheimer's or dementia, too often I felt as though the author's focus was primarily on the "self" as opposed to an unfairness of a situation that many are enduring with much more grace and insight.
It would be interesting to know how the author will view this memoir when she is a senior citizen and her daughter asks her to take off a few weeks to travel cross country to take care of a newborn. I'm not writing that as an insult either. There are an awful lot of things that, as a younger more selfish person, I thought my mother should have been doing that I thought I was owed or that I believed would have been beneficial for her (ostensibly, beneficial for me). Now that I've reached a certain age, I could weep over what I didn't fully understand about my expectations for either of my parents, but especially my mother.
