This Book Is For All Kids, But Especially My Sister Libby. Libby Died. 

I’ve bought this book myself — it’s a children’s book written by a little boy, Jack, about his sister, Libby. In it he asks questions and makes comments in a very honest way. Definitely a must have for those sad moments in life.
