Book 1 of the
Air Awakens Series,
Air Awakens, presently has a Whispersync deal on it for only
$2.98.
The series is authored by Elise Kova. There are 5 books in the series, but none of the rest of them appear to have unusually low priced WS deals. This book (and probably all of them in the series) are oriented toward teens and are fantasy/romance.
You'll save about $15 by buying the WS deal over purchasing the audiobook alone at Audible, where it's $17.95.
The ebook meets my high standards, such as great ratings (4.3-star average at Amazon, from 509 ratings, a substantial number of pages (342), etc.
Here's
the Amazon webpage for the ebook, which page you can go to find out more about the ebook and also grab the WS deal if you're so inclined.
