So incredibly good! I have to say that this one surprised me so much! I didn't expect it to be so mysterious and creepy and just super awesome. Usually I like different type of books, not this genre but when I read the first impression I was intrigued so I had to read it and I am so glad I did. I absolutely loved the characters, specially the sisters but also Tyler. The sisters characters are so complex and interesting and super mysterious that you can't help but to keep reading to know what's going on, why things are happening to them and why all the secrets. The atmosphere and all the details of the "halfway" world or the "in between" were so good that I was transported there and also super creeped out, this author is really good at descriptions of places. I wouldn't say this book is scary but it's pretty close and some might even find it scary so I say read with caution if you scare easily. There are twists that you won't see coming and they are so good. This is one book I am keeping and reading again because I really liked it and will definitely recommend to some friends that like this genre. I would rate this book higher if I could.
