A relative of one of my customers called me from Hawaii to tell me that I had to read this book. I can always tell it is he when I pick up the phone and hear, "Aloha!!!" He didn't want to tell me too much about Little Star by John Ajvide Lindqvist, because he didn't want to spoil anything for me. However, he did want me to call him to discuss the book as soon as I finished it.
After reading it, I have to say that if you like Stephen King, you would enjoy Little Star, which focuses on two girls—one of whom is a sociopath and another who idolizes and wants to be just like her.
