I recently downloaded this book to my Kindle during a road trip. Asking and answering these questions made the time fly! The questions cover a variety of topics, encourage revealing answers, and help spark other conversations. I suppose you could come up with your own questions with some forethought, creativity, and no inhibition, but having this list gives you a quick selection and some off the wall questions. It's especially fun for a road trip or traveling with friends or your significant other.
I rated it at 4-stars because the Kindle edition is expensive- $9.99 is a lot for an electronic list of questions, and there were some minor formatting errors (Example: many questions started with "It" instead of "If" or weren't spaced evenly). There are about 10 questions on the free sample download, but after we went through those I sucked it up and paid for the book for the instantaneous download and entertainment value.
