As Open as a Closed Book

Kamryn witnessed her parents die when she was six. Her father killed her mother, but did he really kill himself, too? She is as open as a closed book now. She doesn't tell anyone much of anything, afraid of being hated. Anthony is her best friend, who heard the gunshots. What happens when he wants to know what really happened to her father? Will she tell him ten years later on the day they died, or will she die first to keep it a secret?
