Loved this one. It's a combination Reality Show and spoof on The Most Dangerous Game. Kitty and a group of other paranormals are asked to star in a reality TV show where they try to convince a skeptic that the supernatural exists. Except that TV show is a front and the producers want to hunt and kill all the supernatural participants and then the non-supernaturals because they're witnesses.
This book was scary. There were moments that were truely terrifying and aside from Kitty I wasn't sure who was going to make it out alive. House of Horrors has the highest body count yet in the Kitty books. Some of those deaths are really sad, because you were introduced to the characters in previous books and grew to like them, they sock you in the gut.
I'm looking forward to seeing how Vaughn deals with the aftermath.
