Our Dark Duet (Monsters of Verity, #2)

by Victoria Schwab

Because she knew a secret: there were two kinds of monsters, the kind that hunted the streets and the kind that lived in your head. She could fight the first, but the second was more dangerous. It was always, always, always a step ahead. It didn’t have teeth or claws, didn’t feed on flesh or blood or hearts. It simply reminded you of what happened when you let people in.
