Hello everyone! I have been on such a long hiatus from writing fanfiction that I am so nervous about this story. This is my first Marvel fanfiction, please let me know what you think and enjoy.
Disclaimer: I do not own anything apart from my OC

As the inferno of fire slowly consumed everything in it's path, not for the first time that evening, Erin couldn't help but think 'why me?'

That thought got even louder as a man with a metal arm grabbed her tightly round the waist and threw them both out the 10th story window.

-Two weeks earlier-

"I have your dinner reservation at Le Caprice booked for 3pm today and I cancelled the drinks with Dreswick as requested sir"

Erin looked over her notepad ensuring she had done everything he had asked of her that morning.

Alexander Pierce barely looked up from his desk as he nodded in agreement "Very well Erin, that will be all"

Realising her dismissal Erin left his office, quietly closing the door behind her... like most days, he barely acknowledged she was there.

Erin had been Mr. Pierce's secretary for four months now after her predecessor went on maternity leave, allowing her to rank up on a semi permanent basis. At first she had been thrilled to be able to work so closely with such an important official, she was picturing emergency state meetings and classified knowledge.

That excitement was quickly unfounded. Whilst he was never rude to her, he had no interest in her as a person and treated her as the walking Google calendar she was but it could have always been worse.

She let out a long sigh as she returned to her own desk which was situated down the short corridor away from his double door, security locked, paranoid haven. Her cup of tea was still hot when she took her first sip, it was the only way she functioned in the morning. You can take the girl out of England but you can never take the English out the girl.

As Erin typed, stopping every now and then to sip her tea, she felt a sense of calm and purpose. She preferred having a task to focus on rather than having to call restaurants and re-arrange cocktail hours which seemed to take up more hours of her day than she ever thought it would.

As she wrote she heard the elevator doors open and someone gradually walk up to her desk; "One moment please" she politely said when the mysterious figure reached her desk, she wanted to finish the sentence she was writing.

She typed the last letter satisfied and looked up with a big smile "How can I he..." the words trailing from her lips unspoken.

Captain America looked back at her with an eyebrow slightly raised waiting for her to continue.

It was odd, they worked for the same company, they were in the same building, well when he wasn't away saving the world but they had never even crossed paths, until now.

She mentally slapped herself into professionalism. She put back on her genuine smile and started her sentence over.

"Captain Rogers, how can I help you?"

Seeing him in the flesh had really taken her by surprise, especially as he was now wearing dark blue jeans, a white t-shirt and a brown leather jacket. If he wasn't 6ft2' and about 240lb of pure muscle, he would be your everyday handsome boy-next-door.

Captain Rogers quickly returned her smile, visibly relaxing "Hi, I need to see Secretary Pierce, has he got a moment?"

Erin reached for the buzzer next to her laptop, pressing it once before softly speaking to the mic "Mr. Pierce, Captain Rogers is here to see you"

After a moment of silence came the response "Send him in"

She stood up, moving round her desk to the corridor opening and smiled at him again "This way Captain"

They walked in comfortable silence as he followed her to Pierce's office, she swiped her key card at the door and waited for the green light to flash allowing her to open it.

She walked slightly through, giving the Captain space to enter as she introduced his presence and asking if either would like a refreshment. When they both declined, Erin silently excused herself, closing the door once again.

The Captain re-emerged around half an hour later, as he came up to her desk she turned her head to smile at him.

As he stopped to look at her he returned the smile "Thank you..." he waited for her name.

"My name is Erin, captain"

"Erin it was a pleasure to meet you" He responded with gentlemanly sincerity.

"Likewise" she returned kindly.

And with that he got in the elevator and nodded at her before the lift doors closed.

After the anomaly in her day Erin continued with her tasks, bidding Pierce goodbye as he went for lunch.

It's not that she found her job boring, working for the world's best intelligence agency was incredible in many ways, she often found herself lucky to be there at all.

Erin was 26 years old and did not consider herself spectacular in any way, her grades have always been average, she didn't have any extraordinary gifts or talents.

She had got where she was by growing up in the military, living around the world and working hard. She was fluent in English, German and French and had met the right kinda people growing up. That was it...she was lucky. Erin got a low level job in S.H.I.E.L.D at 22, passied her basic training, completed all the security checks and worked her arse off.

She just managed to fast track to a higher level position temporarily. In all honesty, she didn't really know where her life was heading or what she wanted to do. She was still figuring that part out.

Before she knew it the end of another day came when the clocked ticked over to 6pm, she gradually filed away her papers and tidied her desk.

As routine, she would always check on Pierce before she left to inform him him she was leaving. Essentially she just wanted to remind him him that he would have to rely on his Google calender until the next morning when she was back in.

She grabbed her handbag, placing the strap over her shoulder and made her way to his door before knocking lightly.

A gravelly voice answered, as it did every evening "Come in".

Erin poked her head round the door "I'm leaving for tonight sir, do you need anything before I go?"

To her surprise he looked up and motioned her with his hand "Please sit for a moment Erin, there is something I need to discuss with you"

A sudden feeling of worry overcame her as she walked in and closed the door, making her way across to his desk and sitting in the available chair.

As she sat there, waiting with her hands clasped tightly in her lap, she could clearly see the tiredness in his face.

Pierce looked up from his paperwork and gave her a polite smile before beginning "Now Erin, you have been a great help these last few months after Stephanie went on leave but I think it's time you go to a more suitable position" His tone was gentle but it did not stop the knot forming in her stomach.

She tried to keep her expression neutral "More suitable, sir?"

He leant back in the chair, relaxing his posture before simply stating "Yes, from now on, I am assigning you to be Captain Roger's personal assistant."

In that instance Erin really couldn't help her jaw slightly dropping with shock "Captain America sir? Why?" She knew better than to question his orders but it was out of her mouth before she could stop it.

Pierce's eyes narrowed slightly "Captain Rogers requires someone to help plan his day to day, his travel, his grocery shopping, his laundry if needs be. Like I said earlier, you have done a great job but I could use someone more experienced, more senior to help me with my work. The Captain is still adapting to every day modern society, he needs someone to help do that, I chose you for that task" He finished, eyeing her carefully to see her reaction.

She thought this over for a split second before responding "I would be honored, sir"

So there we go first chapter! Please let me know what you think, positive comments and constructive criticism all welcome.
