You can get a free audiobook when you create a new account
at Tantor Audio, thru the end of the year. Choose from:
- Glass Houses (Book 1 in the Morganville Vampires series), by Rachel Caine
- The Return of the Gods (Evidence of Extraterrestrial Visitations), by Erich von Daniken
- Containment, by Christian Cantrell
It is all automatic during your account creation (you choose from a list at the bottom of the page), there are no promotion codes needed. You will, however, have to enter your name and address (but no credit card info). You can opt out of their emails or request a digital catalog be sent at the same time.
Tantor has also just released a free app for both iTunes and Android (including one from the Amazon Appstore, but it's not compatible with the Kindle Fire). If you have a compatible device, you can listen to your audiobooks from there (and the app allows you to choose an SD card for downloading, if available) or you can download to your computer via the website.
