What is a good title for my book?

My name is Megan, I am 15 years old. I am writing a book about a foster child named Emily. She is six years old and has been in two foster homes. The last one she was in, She watched her foster mom( molly) be killed by her foster father(Danny,) When she goes back to the children's home she is not the same. Then this couple come to the foster home looking for a child. They can' t have kids. The girl Amy, wants to get a little girl. It takes a while but they end up adopting Emily. Now Emily is home with them and things seem to be going okay. Amy and Michel(Amy's husband) don't know about what happen to Emily. Emily does not know if she should tell them. She is not sure she can trust them yet.
