99 Problems is Runner's Book Bundle. And a fine bundle of books it is.

And what is the Runner's Book Bundle one might ask? It is: 

15 Indie Ebooks in 3 Volumes for 2 Charities

Books by runners, books for runners

And all proceeds go to support the Vermont Foodbank and the 100 Mile Club
 
It is also only happening until July 31st, so do hit it, because while it just might change your life, your support will most certainly change the lives of many others.
