Author's Summary: The Master's Paradox Machine proves to have been a bad influence on the TARDIS, and the Doctor is certain that Martha is the only one who can help him set his ship to rights.
Characters/Pairings: Tenth Doctor/Martha Jones
Recced because: Because it completely caught me by surprise, that's why. Martha goes back to the Doctor and it starts a little too mushy for my liking but, well, you'll see if you read (which you totally should, yes), the ending is excellent. The pace and dialogue is just perfect and the settings that the Doctor and Martha find themselves in are brilliant.
