Dystopian romantic fantasy well done. I love the fairytale carryover of trolls living under a bridge.  And the fear ability is definitely unique. Book has complete, yet minimal world building, interesting characters and storyline, no fluff, action, adventure and emotion. The oppression and caste system are somewhat relable too.  The love interest kept me guessing as she met the characters. I am so happy with the choice and how this book turned out.  I do think book reads YA with minimal descriptions of violence and vague closed door sex scene. However, still thoroughly enjoyable for adults as well. I thoroughly enjoyed reading this book.  My favorite scene reminds me of when the girl gets angry in the movie Fire Starter.
