I recently read Two Girls Down by Louisa Luna, a mystery book out of the norm of my usual reads. While the story kept me engaged with a desire to know what happened to the kidnapped girls, it did not leave any lasting impression. The characters did not have a lot of depth; they also did not grow or learn much. By the end of the story, the events got more perverse. It seemed like it went for more of a shock value than any nuance in human behavior. I enjoyed the mystery to an extent, but I noticed better books exist in this realm. This one will not stay on my bookshelf.
