Twelve Nights at Rotter House

In my opinion, this book was amazing. I loved Felix as a narrator (I tend to like when protagonists are authors; especially horror authors in a horror book)
I thought Felix was pretty funny and reading from his perspective really added to my enjoyment of the story. I feel it's important to note that I may have liked his perspective so much because I actually have almost the exact same viewpoint on the supernatural as his character does, so that may have made it more fun for me to read. 
The banter and overall dialogue between Felix and Thomas was great and fun to read as well. 
 I loved the meta-ness of this book, as well as the overall tone to it. I like when books can make fun of themselves a bit, and that definitely happens throughout this. 
The only thing is the ending, while I did catch a couple of hints that it was coming, it definitely still caught me off guard. That being said, after thinking on it for a bit, I do like the ending, but I can definitely see how it isn't for everyone. Maybe keep that in mind before you pick this one up.
