Prologue

Rose Tyler got up that morning, thinking this has to be the day. The stars are going out and things have got eerily quiet from other worlds in this universe. She has been dimension hopping for over two months now, not always landing on Earth, but the same thing is happening there nonetheless. Rose needs to find The Doctor in her home universe but without a point of reference it is easier said than done. She still wakes up every morning after getting back home in disappointment, thinking that this time will be different, this next jump will take her to her Doctor.

Rose is no longer sure how old she is because sometimes she is stuck for months at a time in whatever dimension she's been in, although somehow she always seems to manage to get home shortly after leaving. No one else that uses the Dimension Cannon can do that, and she thinks it strange but she and the rest of Torchwood don't put much effort into finding out about it because time is running out.

Walking into the Canary Wharf Torchwood building she checks in as she always does and makes her way up to the room the Dimension Cannon is housed in. The same damnable room in which Rose got stuck in this universe, where in her original universe that Torchwood housed the lever room for the ghost shifts. Every time she had to look at that stupid white wall it just made her more determined to get to The Doctor.

We've managed to increase the power to the Dimension Cannon. We think this will help get you farther through the void. Hopefully to the right universe this time," one of the top scientists named Malcolm told Rose confidently.

"You've said that before; we're not going to cause a blackout across the whole south of England this time?" Rose teased. She liked Malcolm; he's been a good friend to her over the years she's spent in Pete's world. He reminds her of the doctor in a mad scientist kind of way.

"No, of course not," he scoffed. "Think bigger Rose, I'm aiming for all of England this time, and possibly some of Scotland and most of Wales. Still trying to figure out how to take out Northern Ireland with it though. It's on a completely different grid that's unconnected because the Irish Sea is in the way, but we all need goals to work on."

Rose laughed at the panicked look on Mickey's face. "Relax, he's only joking."

"Easy for you to say, you didn't have to explain it to Pete."

"No, but I did have to explain to Mum why she missed Eastenders."

"Good point. You probably got it worse than me. Jackie's always been a right terror if someone interrupts her soaps," Mickey conceded.

Rose picked up her controller for the Dimension Cannon and positioned herself ready for the jump, "Well, better wish me luck then."

"Yeah, good luck Rose, and if they have books six and seven of Harry Potter where you end up, pick us up a copy will you?" Mickey wished her luck with something trivial at the end, since anytime he mentioned what she's doing this for, Rose got in worse trouble than normal. It had become a sort of ritual now.

"Will do. And the rest of them while I'm at it. Can read them to Tony." There were three things she missed most that are not in this universe other than The Doctor: Harry Potter, Discworld and the rubbish chips***. There were some Terry Pratchett books here but that series just didn't take off in this universe. She actually tried looking J.K. Rowling up here, just to find she'd been lost to cyber conversion. And,as for the chips, it was just something with the potatoes and there was little she could do about it. At least she did manage to convince a startled Stephanie Meyer to get that file off of her computer and got Twilight published. It's funny, she'd never so much as picked up a book outside school before she met The Doctor, but the TARDIS talked her into reading things she'd like and now Rose reads all the time.

Trying her best to visualise the TARDIS in her head, Rose pressed the button on her controller and she went shooting forward into a portal that appeared in front of her, made of blue sparks, artron energy, a distant part of her brain provided. It was getting freaky how she just knew things sometimes. It's something that has been happening more and more frequently, and something she needed to talk to the Doctor about because she has a sneaking suspicion she isn't even human anymore. If she was honest with herself she'd been changing ever since she looked into the TARDIS. After all, said TARDIS never actually spoke to her before she looked into its heart. She wanted to ask The Doctor about it but the TARDIS advised her not to mention they were speaking so she didn't.

Rose landed rather roughly on the other side, but she was immediately captivated by the sight in front of her, there was what appeared to be a schism in the fabric of reality right in front of her and she could see all of time and space, everything that ever was, is and will be, as well as memories of her time as Bad Wolf. She was inspired; she could feel her mind expanding as she watched and felt her body changing on a cellular level. Her mind filled with all the knowledge the TARDIS had gifted her with which had lain dormant until now. She now had knowledge of trans-temporal physics, temporal engineering, every language in existence, twelve-dimensional mathematics, and a whole host of things one would need to spend hundreds of years at the Time Lord Academy to know.

Rose felt a small hand take hers and she was suddenly aware of her surroundings again. A small boy of around eight years looked up at her as shocked Time Lords began to come to their senses and notice the intruder who had mysteriously appeared in front of them. The little boy tugged at her hand and simply said, "Run."
