So far, this is a really good novel about family survival. As the oldest, Matthew, has spent his growing up years protecting his sisters from their mother. The novel is a letter/diary written by Matthew for his youngest sister Emmy. It opens with a letter to Emmy from Matthew telling her that if she is reading the letter then he has decided she is old enough to know what happened.
Amazon has an author page for Nancy Werlin, something I didn't know about until I went searching for a picture of the novel. The edition that I have and that is offered on Amazon also has a discussion guide at the end of the novel. I haven't read it as I want to read the entire novel first. I did come across a spoiler at the end, don't read it like I did because now that spoiler is stuck in my mind as I read it.
