Land of Monsters By Stacey Marie Brown

I am the monster they fear. And I bow to no one.
​
The world is aware of Princess Raven Haley Scarlet Dragen—twin sister to her charismatic twin brother, Rook, the daughter of the Queen of the Unified Nations, and the offspring of a notorious dark dweller.
Or so they think they know her.
But she has been hiding a secret since she was born—the monsters within. She had to keep them locked away because one desires blood, and the other craves death. They are the reason the President of Russia seeks revenge and wants her dead.
Now the monsters are set free among a world of beasts and darkness.
Ash and Raven are locked in a political game for dominance, a fight that will strip them down, challenge their strength, and rip them apart.
Literally and figuratively.
In a world where magic and monsters lurk in the shadows, Ash and Raven are drawn into a storm of danger, desire, and earth-shattering revelations.
With gruesome creatures hunting them, they must become the most feared monsters out there to survive.
