Kindle freebie

I'm having a book promotion of my new children's picture book, b and d are buddies.  It's free from now until September 11.  I'd love some reviews of the book.  

I wrote this book to help kids learn the difference between these two letters.  There are a few ways out there already to help teach this, but many kids still have trouble with these letters.  Since I learn something best if I've heard a story about it I decided to make a story about b and d.
