So I've been downloading audio books from audible.com for the past few months, haven't listened to any of them but for $15/month you get 1 credit that you can use on any book. I haven't spent any more than that $15/month but have several $30+ books because I make sure to use the credit on the most expensive of books I want.
The one I've downloaded this month is a history of Europe since 1945, narrated by Ralph Cosham. I have only heard his voice in one other place before, and thus look forward to being taught European history by
Brother Jauffre of Weynon Priory.
