Chapter One: The Journal

"Jump! Jump! Jump!"

Chase watched unamused as his siblings were cheering Adam to do the human bulls-eye bounce.

"Get your video-cams out people! You're going to want to document this!" Adam exclaimed as he jumped.

A crash was heard and Chase looked up to see his brother stuck in the wall.

"We so gotta do that again!"

Chase shook his head. The more disasters that happen, the more Adam wants to do the stunt.

"I'll get the ladder." Bree replied, walking off to get the said item.

"Big D will not be happy." Leo stated.

"Neither will mom." Chase pointed out.

Bree came walking back into the living room, struggling to carry the ladder. "A little help guys!"

Chase and Leo immediately went to aid their sister in bringing the ladder over to Adam.

"You two keep the ladder stable. I'll pull him out." Chase directed as he climbed up. Bree and Leo were holding onto the legs, making sure another disaster didn't occur.

Chase grasped onto his brother's legs and grunted as he attempted to pull him out.

"Chase! Ow! What are you doing?!" Adam yelled.

"Trying to get you out! What did you think I was doing?" Chase asked.

"Oh, I thought you were trying to pull my legs off."

Chase rolled his eyes and continued to free his brother.

"What happened here?" Donald asked. Tasha and him had heard a noise and went to investigate. They didn't expect to see Adam stuck in the wall and Chase on a ladder, pulling him out.

"Adam attempted the human bulls-eye bounce." Bree explained. "Unfortunately, he was far from making it into the bulls-eye."

"You four are in big trouble." Tasha said, crossing her arms.

"It was all Adam's idea! I had nothing to do with it! Bree and Leo were the ones who went along with it!" Chase protested. He definitely didn't want to get grounded, especially since he wasn't involved in the silly stunt in the first place.

The two siblings gave their brother a nasty glare.

"Just please get Adam out of there and clean up this mess." Donald stated. "We'll talk about a punishment later on."

Fifteen minutes later and Chase finally succeeded in freeing his brother. However, they weren't out just yet. They had to clean up the mess in the living room that Adam made doing his stunt and then there was the being grounded part.

Overall, the day had turned out not like how Chase wanted it to be.

"Ugh! No phone, no TV, no video games. I'm going to die from boredom!" Bree complained.

"Yeah! Dad banned me from doing any stunts. What else am I supposed to do?" Adam asked.

"Schoolwork, I guess." Leo replied. "If you're Chase." He snickered at the last part.

Bree looked up at her brother. "Hey genius, whatcha working on?"

"There's a science fair coming up at school. I'm going to participate and build the best invention anyone has ever seen!" Chase answered with a grin.

Bree rolled her eyes. "Boring!"

Chase frowned. "It's not boring! It's science!"

"Yeah, which is boring."

Chase ignored his sister's comment. "But I'm having lots of trouble. Creativity-wise that is. These science textbooks from the school show nothing interesting enough that I want to display at the fair. And I really wanted to win the first-place prize."

"What's the big deal? It's just a stupid medal spray-painted to look like gold." Bree remarked.

"To me it's much more than that. This could be my opportunity to become popular at school. Maybe people will finally stop calling me a nerd and take me seriously for once." Chase explained.

"Good luck with that, bro. A science fair will not make you popular. If anything, it'll make you more of a nerd." Adam stated.

"Too bad you don't have a lab where you can create awesome inventions and other technological stuff." Leo replied.

Chase thought about it for a minute. He then closed the textbook in his lap. "Wait a second. What if I do have a lab?"

"Huh?"

"Call me crazy-"

"You're crazy."

Chase glared at Adam before continuing. "Call me crazy, but this mansion is huge. Maybe Dad has a secret lab we don't know about."

"If Dad had a lab, don't you think he would've told us?" Bree said. "Chase, it's a silly idea!"

"What does Big D do again?" Leo asked.

"That's a really good question, Leo." Chase stated. "I actually have no idea. Dad doesn't talk about his job much. He never talks about his job."

"Well then, why don't we ask him?"

"Wait, wait, wait! How does Dad's job relate to Chase participating in a science fair?" Bree asked.

"It doesn't. Chase is just so desperate to win the science fair that he's acting delusional and thinking Dad has a lab." Adam remarked.

"Forget it. I'm going for a walk. Maybe then inspiration will come to me." Chase got up from the couch.

"Or you'll be attacked by a bunch of squirrels."

"Enough, Adam! I am not in the mood!" Chase yelled, walking out the door and slamming it shut behind him.

"This science fair stuff is really getting to him." Leo remarked.

"You know what? I want to find out what Dad does. The curiosity is eating me alive and we probably won't ever find out unless we take action and ask him." Bree stated.

"Or we can interrogate him!"

Bree shook her head. "No, Adam, let's just stick to asking him."

"What if he refuses to talk?" Leo asked.

"Then maybe he's hiding something from us. Why is beyond me."

The cold wind whipped around and the cloudy sky showed signs of rain coming. Chase really wished he had brought his jacket along with him. Now he was going to be cold and wet by the time he goes back home.

"Why did they tease me about the science fair? Can't they see it is really important to me?" He asked aloud.

"They just don't understand. That's all." He mumbled. "They don't understand me."

"If only there was something super extraordinary about me. Then maybe my siblings and everyone else at school would stop teasing me and actually like me for who I am." Chase chuckled at the idea. "Ha! But that would only happen if I had superhuman powers or something like that."

Too deep in his thoughts and not paying attention to where he was going, Chase tripped over a rock and found himself tumbling down a hill and straight into a tree.

"Ugh! Ow! Ooh…that hurt." Chase groaned, rubbing his head. "Great! I'll be cold, wet, and sore all over."

Grabbing one of the tree's branches, Chase pulled himself up off the ground. What he didn't realize was the branch was secretly a lever and when he pushed down on it, the ground a few feet away from him slid open, revealing a secret compartment.

"Whoa…what the?" Chase looked between the branch and the secret compartment, astonished by what just happened.

Curiously, Chase walked toward the secret compartment. He looked inside to see a dusty journal.

"What is this?" He asked, reaching for the journal and blowing the dust off of it. It was a dark blue with a red letter on the cover.

"D." Chase read. "Interesting." He opened the journal and looked at the first page.

Entry One:

I can't believe Donnie kicked me out of the company! Just because of what I did. Now I have nowhere to go. I guess I'll have to figure out a plan. I might even have to fake my own death to do what I'm going to do.

But there's one thing I know for certain, Donnie better watch out because someday I'll be back. I'll be back.

To get my revenge.

-D

Chase's eyes widened after reading. A lot of questions raced through his mind. "Who is this 'D'? And who is this Donnie? What did this person do to get kicked out of a company?"

Chase flipped through the pages of the journal. Some were more entries by the 'D' person and others were sketches of inventions.

This caught Chase's eye.

"Hmm…it seems like this person was an inventor. Look at all these sketches!" An idea came to Chase and he grinned. "I could use one of these for the science fair! It's perfect!"

Suddenly, lightning flashed across the sky and thunder boomed in the distance. Chase felt raindrops falling on his head.

Putting the journal under his arm, Chase began the trek back home.

What he didn't know was that keeping this journal will change everything he ever knew about himself and his family.

And unlock secrets that should have stayed locked forever.

End of Chapter One.
