A woman is found one night in rural Victoria. She has no memory of who she is, or how she came to be bruised, unconscious and alone. The year is 1868. She's a time-traveller. Lucky Holmes loses his ARCHIVE partner on an easy mission and has no help from his boss to retrieve her. He has all of history to search, and a suspicion that she didn't Travel alone. He's also a time traveller. He enlists the help of a friend and a disgraced ex-colleague to hunt through all of time to find her. Shinichi Samejima used to work for ARCHIVE, but was let go after he was forced into a compromising situation by his future self. He's not a time traveller, but he has lived this story before and is trying to avoid the inevitable: living through it again. As they run towards the past, and away from the inevitable future, they uncover tangled answers and old ARCHIVE secrets. They're caught between saving history and changing it, playing as fate and respecting old coincidences. And they all must decide how far they're willing to push history before they risk breaking it.
