This is a fantastic horror book this delivers the scares at a very visceral level. It's a nightmare that everyone can relate to...a home invasion with a sinister twist.

When two female housemates experience what they think is a prank payback from an ex boyfriend, they quickly realize that something much more malevolent is going on. Knocking on the doors but nobody's there. Tapping at the windows, an open window that was previously shut and locked. This author really builds the dread as the women slowly start to succumb to their unwanted visitor.

The great thing about this book is that awesome set-up that has your heart pounding and waiting in tense anticipation for what we all know is not going to end well. That palpable feeling of terror that comes from being stalked, feeling like prey, and not knowing who or where your stalker is.

And when the inevitable happens, it's a terrifying cat and mouse game for escape and survival. Without giving away spoilers, the ending of this book is amazing. It doesn't have a traditional ending or one that you might expect from a book like this. The implications of this ending is just as horrifying as the rest of the book and will have you thinking about it after you've finished reading.

I absolutely enjoyed this scary tale and highly recommend it.
