I checked the different retailers selling my ebooks for any current reviews and was pleasantly surprised.
My $0.99 5-letter words puzzle ebook got this response on May 19, and 5 stars too, on Barnes and Noble:
Fun fun fun
When i first saw this book i didnt think it would be challenging enough for me being the word person that i am, I was so wrong! This book is very fun and challenging there is something for everyone in this book. Highly recommended for kids as well as adults.
Here is the link to that puzzle ebook and the review.
