The book is
Lunch with Charlotte, by Leon Berger. It's made up of information given to the author over a 25 year period, by a survivor of the Holocaust.
Thanks to a big (percentage) markdown on the price of the ebook, the Whispersync deal can be yours for only
$1.99. The math: the ebook is free at the moment, and the Whispersync audio is regularly priced at $1.99. So, the total is
$1.99.
Readers really seem to like the ebook, as it is very highly rated--4.6 stars at Amazon (but from only 16 reviews at the present moment); it has 29 ratings at GoodReads, with an average rating of 4.62!. The audio is rated only slightly less, at 4.4 (but that's from only 5 reviews).
It's a big book (404 pages), so there is a long audio (just short of 10 hours long).
Oh, you might be interested in knowing that the non-Whispersync'd audio at Audible is $19.99. So, this Whispersync deal represents a huge savings, even if you're just interested in the audiobook.
For your convenience, I've got the URL for
the audiobook at Audible for you. And, the best (maybe only, I dunno) place to get the whole deal in one fell swoop is
the ebook page at Amazon.
