The Attic of Secrets

What if your attic held a secret that your parents forbid you to know? What if they swore you could never know? What if it was killing you to know it?

That's life for Vicki. Her parents won't let her in the attic. They never will. But Vicki wants to know why they are so secretive about it. After all, it's just an ordinary attic.
Right?
