I just learned that Canon Press has produced an audio book version of Debbie Maken's Getting Serious About Getting Married. I read this just a little over a year ago, and highly recommend it. It helped to cement my thinking on several topics (including what the "gift of singleness" is), and provided much conversation fodder for my friends and I! Definitely a bit of a shocking book, and one, now that there's an audio version, there's no excuse not to check it out. :) You can even listen to the first chapter for free.

Note: It looks like you might have to wait for your copy of the audio book if you order...it's listed as a pre-order item.
