A/N

Hello readers! Welcome to Tale of Time. I've been planning this story for a while now, but it's only just fully come together recently. I'm planning for this to be a three book series with possible one shots along the way. For updates I'm planning on posting 1 to 2 chapters a week depending on how busy I am.

Disclaimer: I know this idea has been used before by other writers so I won't take credit for the idea of jumping around the Doctor's Timeline. I do not own Doctor Who or any other characters from Doctor Who. I only own my plot, ideas and oc's.

Hope you enjoy!

Lucy was sitting in a corner at her local library. She always loved going there. It was her favourite place to go when she wasn't at home watching one of her favourite shows, Doctor Who. It made her feel calm and safe being surrounded by books. There was one particular corner that was hidden away where she could sit between the shelves and read for hours without anyone disturbing her.

Today was one of those days where it felt like the whole world was against her. She felt like she couldn't do anything right and couldn't concentrate on anything. And seeing as Doctor Who wasn't airing at the moment, Lucy had decided to come to the library to take her mind of the world and lose herself in the pages of a book.

After hours of reading, Lucy was brought out her own little world by someone whispering in her ear.

Lucy.

Lucy looked around to try and find the source of the whispering, but she couldn't see anyone, so she dismissed it and settled back into her book.

Lucy.

Lucy glanced back up and put her book down again. "Hello?" she whispered, wondering if someone was messing with her. When she received no reply, Lucy started to slowly edge her way to the end of the aisle.

When she reached the end, Lucy's mind was spinning with unease and anxiousness. She called again, "Hello?" a little louder than the first time, but there was still no reply.

"This isn't funny, who ever you are," Lucy tucked her long wavy chestnut hair behind her ear before she peeked round the side of the shelf. She furrowed her brows and stepped when she saw no one there and looked down the next few aisles, but found nothing.

Thinking that she had imagined the whole thing, Lucy shook her head slightly and turned back down the aisle to go back to her reading when she saw a small glow emitting from where she had sitting. At first she thought it was a small light, but as she moved closer she saw that the light was hovering just in front of the wall. As she watched, the warm light grew and grew until she couldn't see the wall anymore, just one big smidge of brightness. Lucy contemplated calling for a clerk, but something stopped her. A feeling in her gut pulled her towards her light.

So every so slowly, Lucy inched her way cautiously back to her nook and stopped before the light. Hesitantly, she reached out her hand to touch the light. Lucy gasped as a warm tingly feeling made its way up her arm as she made contact with the light. She quickly pulled her arm away at the shock of it and looked around to see if anyone had heard her. She slowly turned back around to face the light and stood there for a moment staring the strange phenomenon.

Lucy bit her lip and looked down at her hand. She looked back up and after pausing for a moment, slowly reached her arm out again to caress the strange light. This time she didn't pull her arm away, and out of curiosity took a step closer to the light so that her whole arm was in the light. Suddenly, she felt herself being pulled into the light and the world around her fell away until only thing surrounding her was the light.

…

Lucy's vision was filled with bright light. She stumbled forward as it faded and blinked rapidly to get her eyes to focus. When they did, she found herself in a large room with a domed glass ceiling and in the centre of the room was a large white machine with wires and computers spread out around the room. Milling around the room were elegantly dressed people milling around. Lucy couldn't help but feel horribly underdressed in her oversized cream sweater and black leggings.

She was looking at a familiar looking logo on the of the walls when someone bumped into her and made her stumble forward. Someone grabbed her before she could fall and started apologising profusely as she turned around.

"Lucy!" cried the man in front of her. David Tennant stood in front of her in a black tux with the biggest smile on his face.

"When did you get here?" he asked her.

Lucy stared with wide eyes in shock at the man before her as she barely registered what he had said. He repeated the question again before Lucy shook her head slightly and stuttered, "Umm, wha..what do you mean?"

"I mean when did you arrive here? I was wondering if you'd show up. You're never gone for long," He replied happily.

"I...I. Where am I? How did I get here?" Lucy asked wearily, still not understanding quite where she was.

"This is Lazarus' laboratory. He just zapped himself with this sonic micro-field manipulator and... " He trailed off as he saw how confused Lucy was. He bent down slowly and looked at Lucy closely, making her feeling a bit uncomfortable and making her avert her eyes.

Slowly, David asked wearily, "Lucy. Do you know who I am?"

"Um," Lucy swallowed and started playing with her fingers nervously, "David Tennant," Lucy said shakily after a short pause.

"Who's David Tennant? He asked, making a funny face. Lucy looked at him in confusion before she froze as he said, "I'm the Doctor,"

Lucy looked at the Doctor in disbelief before someone behind him caught her eye. Martha Jones standing slightly behind the Doctor, looking exactly the same as she had in the show. Lucy reeled and spun around, going back to examine the room again. It looked just like it did in the show. The stone floor, the glass roof. Everything.

"No. It can't be," Lucy whispered to herself, "This is a dream," She turned back to the Doctor and said, "This is a dream isn't. It has to be..."

"No it isn't," Martha said confused as she stepped forward. She turned to the Doctor and asked, "What is she talking about?"

The Doctor turned to Martha and said, "I don't think she's met us before. I think," the Doctor paused and took in a deep breath. "I think this is her meeting me for the first time time,"

The Doctor turned away from Martha's confused face to look back at Lucy sadly before saying, "Come on. I'll explain everything later. We should go and do those tests on Lazarus,"

Lucy nervously followed the Doctor and Martha up to one of the labs. All the while nervously fiddling with her fingers and thinking over the situation. She must be in a dream. That was the only explanation for it. The Doctor isn't real. He's a made up story for television. Lucy had had Doctor Who dreams before, but nothing as real as this. She sighed as she thought that she would just have to play along until she woke up.

The Doctor stopped and peeked into a room to check it was empty before gesturing for the two women to enter. Martha went in first and as Lucy followed, the Doctor placed his hand on her lower back to guide her inside. Lucy tensed up at the contact and the Doctor immediately took his hand away as he felt her tense and swiftly apologised. Lucy waved it off but the Doctor glanced at her worriedly before gesturing for her to sit on a stool beside one of the lab benches.

After making sure Lucy was comfortable, the Doctor hurried about gathering equipment to test Lazarus' DNA. After taking a swab of Martha's hand from where Lazarus had kissed if earlier, the Doctor inserted the sample and brought up an image of Lazarus' DNA on a computer screen.

After studying the same for a while, the Doctor mumbled, "Amazing" as he studied the DNA strand on the screen.

"What," Martha asked confused without looking up from the screen as she leaned lazily on the bench.

"Lazarus's DNA," The Doctor said matter of factly as he leaned on the table.

Martha sighed as she looked on at the screen, "I can't see anything different."

"Look at it!" The Doctor said annoyed.

"Keep watching," Lucy mumbled to herself as she sat rubbing her chest at the aching feeling she had.

Martha glanced up at the Doctor briefly in annoyance, having not heard Lucy's remark, before looking back at the screen again. Just as she looked back, the screen flashed and they watched as the strands in Lazarus' DNA rearranged themselves.

"Oh my god!" Martha gasped, Did that just change?" She looked back at Lucy and the Doctor as he nodded and mumbled in affirmation. Martha looked back at the screen in confusion as she whispered, "But it can't have..."

"But it did," The Doctor answered as he stared intently at the screen before him, examining the sample closely.

Martha, still in denial of what she saw shot back, "It's impossible,"

In retaliation of Martha's denial, the Doctor looked at her and replied, 'And that's two impossible things we've seen so far tonight," His expression then changed to a grin as he asked excitedly, "Don't you love it when that happens?"

Lucy gave a small giggle at the Doctors giddiness before dropping her hand and looking down at her lap quickly when the Doctor glanced back at her, still smiling. Martha however, was not looking as joyful as she stated, "That means Lazarus has changed his own molecular patterns"

The Doctor turned to Martha and stated matter of factly without breath, "Hypersonic sound waves to destabilise the cell structure then a meta-genic program to manipulate the coding in the protein strands. Basically, he hacked into his own genes and instructed them to rejuvenate,"

Martha shook her head as she looked back at the screen. "But they're still mutating now," she pointed out as she gestured to the shifting strand.

"Because he missed something," The Doctor looked off into space in thought as he said slowly, "Something in his DNA has been activated and won't let him stabilise. Something that's trying to change him," Lucy could see the Doctor's mind ticking over as a million thought went through his head at once.

Martha stared at the Doctor and after a moment asked, fearing the answer, "Change him into what"

The Doctor sighed as he looked back at Lucy sitting on the stool and said, "I don't know, but i think we need to find out,"

Martha eyes went wide as she remembered something from earlier, "That woman said they were going upstairs," Martha said, fearing the worst.

"Let's go," the Doctor replied quickly as he ran for the door and disappeared around the corner. Martha was about to follow after him when she noticed Lucy hadn't moved and asked, "You coming or what?"

Lucy got up from her stool just as the Doctor poked his head back round the corner and said "Well, come on then!"
