Bill Walker is the author is A Note From An Old Acquaintance. It was a book I thoroughly enjoyed, read my review here.
Today the author contacted me, to let me know, the Kindle edition of this fantastic story is on sale at Amazon for $4.99! That is super cheap!!!
Here is the amazon link. (It says $6.99 on the website, but Bill stated me $4.99)
Point is, get a copy! It's worth it either way!
