Nothing to Fall Back On: The Life and Times of a Perpetual Optimist Book

I adore Betsy Carter's writing style. I've read and enjoyed every fiction book she's ever written, and once those were all read, I got my hands on this nonfiction memoir of hers. Her trademark style is still there, still enjoyable. But for some reason, she decided to write her memoir entirely out of order, in what seems to me to be an absolutely random order. I can't figure out why she did this, as it detracts from the book (you have to re-orient yourself at the start of every chapter), and I don't see what it adds to the book. Despite this odd stylistic decision, I still zipped through this book. I don't think I came out of it any more intelligent or emotionally enriched, but I still liked it.
