I only just caught wind of this (because I suck at reading my email), but my friend, Super Author Eric James Stone, is doing a Book Bomb for a charity anthology today. The Gruff Variations are stories based around the three billy goats gruff written by a bunch of badass sci-fi and fantasy writers.

For more details, this is what Eric had to say: http://www.ericjamesstone.com/blog/2012/04/19/buy-the-gruff-variations-today/ 

It is for charity, and it has a ton of short stories by some really amazing writers, including other friends of mine like Hogo-Nebula-Campbell-Motortrend Car of the Year nominated Super Author Brad Torgersen.
