Chapter 1

A woman was walking past the busy people and made her way to the Grand Mall Station, located in New York. How her granddaughter could stand this place, she did not know, but she knew that she herself hated New York. It was simply too busy and crowded for her tastes. She much preferred the country life over that. It was quiet and simple and peaceful. Perhaps youngsters liked the surroundings of New York, but she most certainly didn't. But maybe with time, she could perhaps adjust herself to the bright and loud surroundings of New York.

Once she arrived at the candy store, 'Sweet on America', she walked in with the intent of finding Sally Jackson. But on seeing the countless sweets there were, she couldn't resist, but pick a few sweets up. They look good and unique, she justified to herself. Her dentist could go and screw himself. Who was he to tell her that she couldn't have any sweets! She made her way to the counter and saw her granddaughter with a smile on her face as her customer walked off.

"Hello Selene, long time no see," she greeted cordially, taking in the pleasure of seeing her granddaughter's gobsmacked face. "How long has it been? 5 years? 6? 7?"

"Grandmother!" gasped Sally, surprised. "What are you doing here?"

"I'm here to buy sweets, of course!" she said sarcastically, before she said flatly, "Sally, we should talk. We have a lot to discuss don't you think? It's been 7 years, I believe."

"Um, yes we do," Sally said nervously, shuffling boxes of sweets, "Why are you? If you're here to drag me back home, I'm not going back. "

"Oh quit rambling child!" she snapped. Her granddaughter had run off when she was 18, but she knew it was all because of that boy she enamoured with. That boy. She was going to kill him once she finds him. "I'm not here to take you back if that's what you're worried about."

"Yes, grandmother," she complied with a slight frown. "I can't leave the shop until 3 though. I have to cover my shift."

Sally's grandmother waved her hands about dismissively. "Oh, you don't worry about that, dear. Your friend Suzy is coming."

"What?!" yelled out Sally in surprise, eyes wild. "Don't tell me-"

"Silence, young lady," she said, looking at the clock. It was 12. "She should be coming now."

Just as she said that a blonde woman came in hurrying. "Oh I'm not am I? Jesus, Sally you should've warned me if your husband was sick. I can understand, y'know. You better get going!"

Sally looked at her, bewildered. Her husband was off on a weekend vacation with a couple of his friends, something she was glad about.

"Yes, Sally. It's best to get going now," her grandmother said, gesturing to the door.

Suzy looked at her colleague with a look of question. "Who's that?"

"Oh, that's my grandmother, Harriet Black."
