Audio books are one of those strange, enigmatic creatures whose popularity depends not on the customers themselves, but on the core popularity of the book they are based on. If the book isn’t doing well (if there was an audio version at all) its life will be short lived.

But, oh what a life to lead!

Sometimes the audio is read by a troupe of actors or a recognized celebrity and most times by the authors themselves. Business books tend to have the least amount of books on audio. Perhaps it’s because business is timely and most books don’t have the longevity. Perhaps it could be due to the content which is hard to convey in audio form. Whichever the cases may be… here are last month’s best sellers available in audio form:

No. 4 – Rich Dad’s Increase Your Financial I.Q.: Get Smarter with Your Money by Robert T. Kiyosaki and Dave Mallow (Abridged on 3 CDs)

No. 8 – Reinventing the Body, Resurrecting the Soul: How to Create a New You by Deepak Chopra (Unabridged)

No. 18 – What Got You Here Won’t Get You There: How Successful People Become Even More Successful by Marshall Goldsmith and Mark Reiter (Abridged on 5 CDs)
