My life as Lucile Smith

Lucile is a 16 year old girl. Also known as dead Lucy because people can still see her. Mainly her best friend. But she is dead to everybody else that knows her. Mimi can see Lucy everywhere. She is the only one that doesn't know she is dead. But when they first became friends they made a promise. The promise was if one of them died the other one would kill them self. But Mimi already knew Lucy was dead, Mimi had already did the promise but didn't tell Lucy. Mimi wanted to make sure that Lucy remembered the promise. This is kinda a teen fiction and weird. I just labeled it as teen fiction cause they killed themselves when they were teens. Now they kill anyone that crosses over in the house if the Browns.
