Opening a book with a title that was missing a single letter on it's cover, Twilight picks up a rather interesting passion while studying for the entrance exam.

That's when things start to slowly 'grow' out of control.

Desert Mirage lives in a world full of guns, lasers, explosives and people competing to be the best of the best. There she excels at what she does: hunting. She started as a nobody, and yet became one of the most sought-after gunslingers.

Sunset Shimmer was practically born the best of the best. Selected by none other than Princess Celestia to be her prized student... until she ran away to another world in search of power. Through trials and suffering she was eventually taught humility and friendship.

At first blush, they don't have much in common. But their connection runs deep, and sooner or later it will change their worlds forever.
