"Variant" is a short story, just so you know. You can get it for free if you're willing to jump through some major hoops. Check out the terms here.
http://johnaugust.com/variant (scroll down to Why Not Free?) I think I'll pass on that particular freebie offer.

I sampled this last night, loved it, and went ahead and 1-clicked.
I don't usually bother with short stories because they tend to seem overpriced to me when you can get full-length books for free, a cent, 80 cents, 99 cents, etc. - but this one is worth it. Its multiple five-star reviews on Amazon (now including mine) are a testament to that fact.
And the author actually isn't just any old Joe Schmo - it turns out he was the screenwriter for several major movies (Go, Big Fish, Charlie and the Chocolate Factory, Corpse Bride, etc.). That's a pretty impressive résumé, but this little e-book represents his finest work yet (IMO).
The Variant ended up being a major surprise for me, and it's one I recommend wholeheartedly despite its brief length.
