This is my first NT fic, and it's been kicking around in my head for awhile. A note about the title: it was part of some sort of "Gilmore Girls" spoof sort of idea that I had, and it describes Abigail and Sarah anyway, since, well, they're Chase girls. RR…no flames please!

Chapter One

"'Overshadowed' is my middle name," Sarah Chase had always said. In reality, her middle name was Elisabeth, but she felt that Overshadowed would be far more accurate. Her sister Abigail was thirteen years her senior, beautiful, smart, and now world-famous. Sarah was quirky and clever and witty and such, but a gawky teen nonetheless. A gawky, overlooked, overshadowed teen.

For her whole life, her parents, relatives, and even friends had counted on Abigail unrelentingly—she was their heroine, their champion. The homecoming queen, the role model for countless younger girls. This whole Declaration of Independence/treasure mess only added to her superhero appeal.

Gunther and Hilda Chase were thrilled with Abigail's newfound fame and subsequent marriage and insisted that Sarah spend the summer with her dear older sister. They were getting old, they said, and it was time for them to settle down, to let the other workers run the shop. They didn't need to watch a rambunctious teen for another summer. Besides, Sarah could learn something from Abigail—Sarah was never clear what, exactly. How to be beautiful? Abigail hadn't learned that—she was just born that way. How to be smart? Sarah snorted. Abby was intelligent, she supposed, but Sarah considered herself far wittier. How to cause the country extreme inconvience? Well, there was something Abby was good at.

Sarah hadn't met the Husband since the wedding. The ceremony had been extreme anguish—FBI helicopters landing on the courtyard lawn, endless vows in both English and German (Gunther and Hilda insisted) and best man Riley's cell phone going off right before the I-dos. Sarah had drunk about fourteen Vanilla Cokes from the open bar and had to go to the bathroom thrice. In general, it was very boring and long, which was probably what the summer would be like.

Come June twenty-second, Sarah was standing in front of the Gates-Chases' giant new mansion—ridiculously large for three people. Or four, counting her.

She reached up to the intimidating brass knocker and knocked twice. There was no answer.

"IT'S SARAAAAAAH!" she shouted at the top of her lungs. After what seemed like an eternity, an unshaven Riley answered the door. His eyes were barely open, he was still in his pajamas, and he had a slice of pizza crammed into his mouth.

Sarah checked her watch. One o'clock P.M.

"Hey, Riley," she said. "It's Sarah, in case you don't remember. Sarah…Chase." Riley started rubbing his face and squinting at her. "Abigail's sister. I'm spending the summer with you guys."

He stood there for a few seconds before turning around and wandering off.

"Oh, Sarah!" She glanced up the vast staircase and saw her older sister sweeping down towards her. "How are you? Let me get your luggage."

"I'm good," muttered Sarah grudgingly as Abigail picked up her bags. "What…you don't have a butler?"

Abigail laughed. Her parents called her laugh melodious. Sarah just thought it was annoying. "Don't be absurd. What would we need a butler for?"

Sarah decided to be honest. "Babysitting Riley?"

Another laugh. "Yes, I suppose one might come in handy then!" She motioned for Sarah to follow her inside and closed the door. "You'll have to forgive Riley," she whispered to her little sister. "He's a tad hung over."

Sarah groaned. So this would be summer with Mr. and Mrs. Know-it-All and a drunken guy.

Abigail set her bags down by the stairs. "Ben will be with us shortly. He's on the phone with the university but after he's done we can all go out to lunch together."

"The university?"

"Yes, they want us to give a talk on it. Finding the treasure, you know. We're absolutely delighted. It's so wonderful to be able to share our experiences with the world."

The stupid treasure had put her normally perky sister in a state of permanent, verbose euphoria, Sarah decided. She groaned again. This was going to be one long summer.
