The Twisted Sisters

We are Susanne Valenti and Caroline Peckham — sisters, co-authors, and professional chaos creators behind dark romance worlds that are dangerously easy to get lost in.

From paranormal academies to obsessive, emotionally volatile romance, we write stories full of morally questionable men, unhinged chemistry, and heroines who refuse to back down.
