Sterling Slick is the product of a earth pony and a changeling. Because of this, he has the ability to change into any pony he wants. This becomes effective when he joins the intelligence service and save the land of Equestria as the best spy out there, though he'll need help with this mission and might even encounter romance.

Prologue and Chapter 1 is up mainly to see what people think. I was hesitant to post till full story is done but it just isn't getting done fast enough. If enough people like the story, it might give me more motivation to work on this more than other projects.
