I got this book free thanks to a heads up from FreeBooksy!
If you like creepy without graphic violence or sex THIS is the book I recommend. It's Young Adult so the language is clean, the violence is tame, and there's no sex. It's just downright creepy.
I recommend it so highly I don't want to spoil it!
I will say, however, don't feel rushed to read the sequel. It serves as a background to this book and it's really not as good. Necessary, but sort of boring. I'm hoping that the 3rd book is better!
