Creepy! I was not expecting to be wigged out with this book. That does not happen very often. Especially for a 'young adult' book! 
 Kate is a young Amish woman who was ready to branch out and see the world with her friend Elijah. She is so very excited for her Rumspringa and dreams of going to the movies, fun clothes, etc. But the world is rapidly changing in ways no one expected. When a couple of young men don't return home one night, the community begins to learn of something very...wrong and bloody. Fearful of what is happening the Amish community closes their gates to the outside world in self preservation. After saving and hiding a young man, Alex, Katie has broken the Elders ruling. She is determined to learn the truth. But it comes with some high risks. 
 Kate learns that what is happening is that people are turning into 'vampires.' These are very different from vampires I am used to. And with how they operate and do rapid town turning, it reminds me of zombies. So in my mind they are a scary hybrid. 
 The story is fast paced and wonderful. It doesn't let go for an instant! The connecting toward Kate is strong and easy to step into her shoes and experience all the terrors she goes through. And to think, this is the beginning! The is a sequel to go read next! 
 Read this at night, alone. If you can do that and are not spooked. A harden horror fan might not be granted but I have always enjoyed a good scare and that is so hard to find in books. This is decent there. And being a young adult novel, more appropriate. If you scare easy, read during the day, when someone else is home. Regardless, read this!
