Tweedledum and Tweedledee (Emma Frost Book 6) by Willow Rose is a truly horrifying book. I gave it five stars because it kept me guessing. It reveals a lot of the cruelty of children & men toward something different & fearful.
I purchased a copy of this book the end of December. When I did start reading it, I finished it overnight.
