The 10th book on my Empty Shelf is "Quicksand" by Iris Johansen.
This book did not have a nice tied up with a bow ending. So if you expect that, which I was, you may be disappointed. However, the more I think about it, the more I am ok with it. Life doesn't end every day with all problems solved, so why should I expect every book to give me that? This book, even on tape (not my preferred way to take in a story), held my interest and was a good "read".
Can you like a book that doesn't tie up all problems before "The End"? I'm starting to think maybe I can.
