I just finished reading a sweet, funny, wise book called My Friend, My Hero, My Dad: The Extraordinary Influence of an Ordinary Man by Stephen Altrogge. (Stephen and his dad, Mark, write a blog called The Blazing Center that I enjoy.)
It is a quick read (about 86 pages), and the Kindle edition was only 99 cents. (Even if you don't have a Kindle, you could read it on your computer on a free Kindle reader from Amazon. It doesn't look like this book is in print anymore.)
I recommend it. It made me tear up because it is so sweet. :)
