A/N: Sorry for keeping y'all waiting. I had school and job hunting to do. Now, it appears that the job hunting may be over as of today, as I've been offered a job. I will be unable to update as frequently as some of you may want, but I'll update periodically over the next several months, most likely once or twice a month. It will take me longer to write each chapter, as I am trying my hand at writing longer chapters than I typically do. So please bare with me. I'm trying to do a lot of things at the same time while trying to please you, my fans. I'll stop this rambling right here, right now so that y'all can get to what you really want, the story. I hope y'all enjoy!

Harry Potter and the Great Heathen Army

Chapter 1: Lost in New York

13 years Later: August 18th, 2018

Hermione's POV:

Hermione had been excited for this trip. She had always been fascinated by the City of New York, and the United States as a whole. The culture was different from that of England, and the history was rich here. She wanted to go to every museum, get her hands on as many books as she could, see all of the historical sites, including the battlefield at Saratoga. She wanted to soak up as much knowledge as she could, because to her, knowledge was power.

Hermione's parents knew how much she wanted to visit New York, and that desire, they discovered, only increased after they told her she had been born in New York while they were on vacation. They decided that, once Hermione was old enough to really appreciate, and enjoy a trip to New York, without all of the fussing and crying you might hear at the airport and on the plane, which they figured would be a nightmare with a small child going from London to New York City on a non-stop flight. And it would be expensive. So they waited several years and put some money aside for the big trip. It erwas going to be a wonderful trip, they thought, as they believed their daughter was old enough and responsible enough to be a good girl on the trip. After all, she was a big girl now, 13 years old, and they believed she'd behave herself, since it was part of her birthday present.

The trip was excellent. They had seen almost everything Hermione had wanted to see. They had gone to several different restaurants, featuring foods from every region of the country. Hermione's favorites included Texas Barbecue and southern Comfort food. There was just something about the way southerners prepared their food that made her like it so much. She liked one particular diner so much that they went to it several times on the trip. It was Metro Diner, and they found out it had appeared on Diners, Drive ins, and Dives, and the food and atmosphere was as advertised, if not better than advertised, by the show. The portions were big, but it was so good that she couldn't stop eating it. She felt like her best friend Ron Weasley, pictured herself eating like him, and had to laugh at it. She had successfully completed the 12-inch Pancake Challenge for breakfast one morning. Then she had the Holy Davolli Burger for lunch. A half pound burger patty sandwiched in between two grilled cheese sandwiches with bacon and tomato (the sandwiches were the buns). She had them replace the lettuce/pickle slaw (which included mayo) with lettuce, pickles, and barbecue sauce. It was good. Then she had the Pittsburgh Steak Salad for dinner. She had also gotten the Yo Halleh for breakfast one morning. It was French toast made out of Halleh bread, stuffed with a cream cheese and banana mixture and topped with a blueberry-strawberry compote, and you can't forget the powdered sugar. She knew Ron would love this place and made a mental note to bring Harry and Ron here some day. Maybe even Ron's little sister Ginny could join them too.

Today, August 18th, was her 13th birthday, and it started like any other day during the trip. Sure, the trip was nearing it's end, as they have to get home in time for Hermione to get ready for her 3rd year at Hogwarts, and her parents had to get back to their dental practice.

Stupid ADHD. She was getting off track. She couldn't believe she had ADHD, especially since she was so good with her studies. But it was beginning to act up considering she was out of her medication and needed to get some more once they got back to England.

So, the day started off normal for the vacation, but then the crowd pressed in at Times Square, and her mind began to wander again. It was pouring down rain, but they were used to rain in England, so they weren't going to let it ruin their day.

Hermione was cold, soaking wet, tired, and hungry. All of which contributed to her falling behind her parents. They told her to catch up, even her father yelled at her for failing to do so, even grabbing her arm a couple times. But the cold, wetness, hunger, and tiredness kept slowing her down along with the crazy crowd. And of course, her mind kept on wandering, and, you guessed it, she got separated from her parents. She tried to find them. She searched the crowd for them, but couldn't see them. There were no police officers in the area, and even if she could find a payphone, it doesn't mean that it would work, and besides, she had no money for one even if she found a working one. Everyone was in too much of a hurry to notice that she might need help. "This is New York City", she thought.

She just kept walking, turning corners periodically, hoping she'd get lucky and find them soon. But her thoughts slowly turned back to her friends, Harry and Ron, and wishing they were here to at least keep her company and help her find her way back to her parents. She knew they'd be angry with her and punish her for disobeying and not staying close to them, especially in an unfamiliar city.

Not only did her thoughts travel back to Harry and Ron themselves, and wishing they were here, but they also went back to the events of the last couple years.

A/N: Just a little cliffhanger for y'all.
