Envy is an Empty Coffin novel by Gregg Olsen. It’s about a pair of telepathic twin sisters who uncover the case of their friends death. Their names are Hayley and Taylor Ryan. Their friend is Katie. What they try to figure out if it was suicide or murder. I know the answer I’m just not telling you because I don’t put spoilers in my book reviews. This is one of the very few mystery books that I have read. Most of the novels that I have read are romance. This time I wanted to try something different. Katie had very low self esteem and also engaged in self harm. Because of this many people assumed that her death was from suicide. One of the things that I didn’t like about this story was how boring the twins personalities were. Even though Katie’s “best friend” was quite a snob I still found her more entertaining to read about than Hayley and Taylor. I also found the twins powers hard to understand while I was reading about them. I didn’t understand how they figured out what their powers were telling them because it was hard to connect to the situation. But the case itself was okay. It was a little predictable but it wasn’t as predictable as Scooby Doo. But if you compare it to Law and Order, it’s very predictable. I would give this book 2 stars out of 5.
