It's been a wild, wild month - you all have spanned the realms of possibility and once again blown us away with your visions of "what might have been." But as the Doctor knows too well, the walls between the universes have to close, and now's the moment:

The AU Challenge is now closed!

Every month you continue to amaze us: for those days when you just swear you were born in the wrong universe, you can find all the entries under the challenge: au tag, or just click here.

New challenge up shortly - we've brought them back, but where on Earth are we bringing them back to? 

The walls have closed. We've called our boys home from their wanderings - but what if they don't quite make it home? The TARDIS can be a fickle thing, and Jack's teleport - well, it's been turned on and off so may times, who's to say it won't suddenly decide to give up the ghost. It's the space-time equivalent of a flat tire, only who knows where and when you'll get stuck?

Desert islands. Strange hotels in the middle of nowhere, with nary a mechanic in sight. Remote mountain tops. New planets, with the TARDIS translation circuit on the fritz. Centuries ahead of their time - or centuries behind it - or really, for the Doctor, stuck on the slow path in any single century at all.

Strand them alone, and see how they cope. Strand them together and see how long it takes them to argue over the proper way to change a tire (or the TARDIS-equivalent). Strand them separately and watch them do what it takes to find each other again, or have one strand the other, and see who cracks first.

This month, the Doctor and Jack end up Lost - or just plain lost. Strand them somewhere, anywhere, and show us just how resourceful they can be. (Jack is just full of resources. You'd be amazed what he can do with some lubricant and a tool belt. Hey - get those minds out of the gutter!)

As a gentle reminder, please don't crosspost stories for this challenge elsewhere until the challenge closes about one month from now. And don't forget - leave a comment in THIS post and tell us what you think the next challenge should be!
