Karma's A Tricky Thing

There once was a girl named Rachel who had everything she ever needed: A loving family, a best friend, and never a bad day in sight. Some might say she was the luckiest girl alive. Then, after her father was shot during a bank robbery and her mother died of sickness a year later, Rachel thought her luck had run out.
Luckily, her parents left her in the care of her maternal uncle, Alfred Pennyworth, who was also the newfound guardian of her best friend, Bruce Wayne. As such, Rachel came to live with them at Wayne Manor, which made her friendship with Bruce stronger than ever. Now, see how these two friends help each other save their home in honor of the family they lost and the one they gained.
