Query: A ROLLERCOASTER RIDE THAT NEVER LETS UP!

I LOVED this book! It was so unbelievable great. I totally loved and identified with the character Wendy. The book is rich in atmosphere and while it isn't really scary, its super entertaining! Its kind of a horror/action hybrid. The writing is great. It was a really fun read, I read it in only two days! I would highly recommend it if your looking for a suspensful horror novel, it also has great humor in it too.
