Mystery of the Mirror

But when she finds a girl that has mysteriously appeared in her mirror, she realizes that things might be stranger than they seem. As Danielle, her cousin Macy, and their new friend from the mirror try to keep the situation under their control, the opposite happens, and the unavoidable unfolds.

Introduction:
"Whoo-pee!" Danielle Fosggare yelled, swooshing through the air on a rope swing tied to a rafter in her father's barn. She jumped off and landed on a board nailed between two poles holding up the roof. "You can go now, Macy," She yelled to her best friend and cousin waiting on a run-down platform on the other side of the barn. Macy immediately jumped onto the rope and swung back and forth. "Whee!" she shouted, twirling around and around.
She waited until she slowed down to a stop before jumping to stand next to Danielle. "Your dad's Fun Park is the best," she said. "You're so lucky. I wish MY dad was an inventor."
"It IS nice," Danielle admitted. "But try not to think about it. There's always a time where one of his wacky machines comes out bad. I know, let's go get us each a Cake-Pop!"
"All right!" Macy cheered, and they skipped off to the Cake-Pop Machine.
Inserting two quarters into the slot, Danielle waited until the plastic bags dropped out of the opening, grabbed them, and, handing one to Macy, ripped hers open. "Oh, I got lemon!" she squealed, while Macy groaned, “Strawberry AGAIN? That's all I ever get."
"Well, at least you didn't get chocolate," Danielle said, biting the frosting off of the ball of cake at the end of her stick. "That's the most common flavor that the machine makes."
Macy giggled. "I was going to ask you if you wanted to trade, but you've already gotten your mouth on yours, so you can bet I'm not going to now."
Danielle laughed, too. "You know I wouldn't have anyways. Lemon is my favorite." Suddenly, both girls heard the unmistakable sound of Danielle's mother's voice.
"Danielle! Where are you? It's time for lunch!"
Danielle jumped. "I've gotta go. Mom never lets me be late for meals. I'll probably see you when we have your family over tomorrow."
"All right, see you then," Macy yelled as Danielle sprinted off. "Bye!"
"Bye!" Danielle shouted, slamming the screen door to her family's house.
