Coming back from a hectic job, the crew of Serenity experience a ship-wide malfunction as a bizarre incident occurs in space around them. Eventually all of the ship's systems clear and they think nothing of it, that is until they discover they've taken on a rather interesting hitchhiker.

An MLP/ Firefly crossover story, if that wasn't obvious.
I appreciate the story being shared around, commented on, liked, enjoyed, all that jazz.
