Monsters are real. Great White sharks lurk off popular beaches - killer crocodiles and man-eating pythons prowl the Everglades.

But for Abigail O'Neil, raised on the swamp, the most terrifying monster was her own father - a black-market croc-farmer notorious for feeding unwary victims to his jagged-toothed pets.

Growing-up privy to unspeakable horror, when Abigail finally fled home, she thought she'd left it all behind.

But now someone is stalking her - and they know all her deepest, darkest secrets.

There are always worse monsters - bigger sharks - larger crocodiles.

And there is always one more human-monster deadlier than the last.

Now Abigail must find the monster in herself.

Or she won't survive the Apex Apocalypse.
