The Third Knock (Black Eyed Children Series Book 3)

Ruby is on the run, but the black eyed children haven't forgotten her...
Battered and wheelchair bound, Ruby has now found refuge in a dingy apartment building. Her brain is wracked by nightmares and an all-consuming sense of paranoia. The days are marked by a simple routine of eating, taking pain medication, finishing rudimentary tasks at her day job, and most importantly, to not let them in.

Yet the demonic children with their pool-black eyes have not forgotten her. They are determined to break down every ounce of sanity until nothing remains. The evil children want Ruby. And they won't rest until they finally possess her.

Thunderous storms beat relentlessly against the building's windows, and a newly gruesome monster suddenly appears. Its wide, grinning teeth and bloody smile haunt Ruby's every waking hour ... or is this new abomination a figment of her increasingly fragile imagination?

With their eerily child-like voices calling out to her, and the grisly creature playing mind-games, Ruby must find a way to banish these horrific fiends once and for all. At her wits end, and physically broken, she will have to keep the children out of her house, and out of her head. 
But they are terribly relentless. And all they really want is to come in...
