A Spool of Blue Thread

First I thought this was a book about a problem child. Then I thought: a woman, growing old. Then: oh, a family. Next: a house. Later: a family and its past. But in fact it is about all of this - of course - and the problem child finds a neat resolution too, at the very end of the book.
But even more so, like with all of Anne Tylers books, it is about endearingly normal, endearingly weird people. And she is looking back on life itself.
