Dear my sweet Serena.....

The marks

Savanna was walking along an old townhouse with photos of the owners on the outside of the townhouse.
"Weird"
That's all she said before she heard running behind her.
This is where she met Serena.
She was a short brown haired girl with dark blue eyes.
"Hi! I'm Serena! Nice to meet you! Are you new here?"
Serena said with such joy in her voice
Savanna was 10 while Serena was 9
"Hello Serena, I'm savanna, but people call me savy for short. And to answer your question, I am new here, I was looking around the neighborhood"
Savanna said smiling a bit then walking away.
Serena was catching up
"Savanna! Don't go down there"
Everything went black after she went passed the townhouse
Savanna noticed the marks on Serena's arms when she pulled her out of the blackness.
"No one has ever passed down there"
"NO ONE"
Savanna woke up in her house
She was shaking from fear.
She remembered the marks.
It spelled out,
"Hello savanna"
The cuts look about, the weeks old.
She moved in right after she seen the townhouse
Those marks aren't old....
