To Stand in a Fall How Far Can We Fall?

"Noah's life was blissfully ordinary, something she had always taken for granted. Then the Fall. Life was turned upside down in a day, as entire cities are swallowed up by the Earth as sink holes appear without rhyme or reason, and there is something alive down there. Noah and a local cop, Duke, must learn to rely on one another for survival, if they can make it out alive at all, as creatures of unknown origin begin a feast on mankind. And as time soldiers on, Noah is faced with a terrible reality: sometimes, the monsters are human."--
