This was by far and without comparison the creepiest story I have ever read! So scary and although paranormal, so incredibly realistic, it left me with creepy feelings and unpleasant goosebumps. I loved every moment of it! Freaking amazing.
The authors could not have done a better job on character development and the plot execution. So short and so much in there, it's amazing. The alternating point of view contributes greatly to the character development and the creepiness factor, and seamlessly carries on the plot.
The story revolves around three people Rory, Scott and Calypso, although Calypso plays a lesser role in the whole story, but her mere presence determines the actions of the other two.
I cannot say much more without giving spoilers but I can say that I would not recommend reading this before going to bed. The authors took a scary realistic plot that could happen at any time and gave it a paranormal/urban fantasy twist and wow.
I could see this evolving into a creepy, super creepy series following the creepiest main character ever invented. Seriously fantastic idea, execution and writing style to match it.
