Rec: Me & Emma by Elizabeth Flock http://www.amazon.com/Me-Emma-Elizabeth-Flock/dp/0778320820This one I will never forget reading.
It's a story about a little girl and her sister in a family of abuse.
Her father is murdered and her mother marries another man who can only be described as a wicked stepfather.
Your heart breaks for these children, hoping that they will one day get out of this horrible family life.
Try not to read anything about this book for fear of spoiling the ending.
It's a surprise ending that as most other reviewers have said, will hit you like a ton of bricks.
