Behind The Door

"I am Spencer Noon. I am thirteen years old. I live in the USA, My parents are divorced. I just moved to LA, and into a duplex. I met Athena Johnson. We went through a portal."
When Spencer, an only child that moves into a duplex with her mom meets the girl whose family she shares a duplex with, a lot happens. She learns a lot about her new friend, uncovers an old family secret, and well, kind of travels through the fabric of time and space. But you'll learn more about that later.
