So, yeah, a continuation of the "Amish teenage girl fights vampires" that started with The Hallowed Ones, and you know what? Not quite as good as the first book, but still a heckuva romp, still entertaining, still with a strong, smart female protagonist, and I am just fine with that.
This book takes young Amish Katie out of her Amish community and into the larger world, which she's never been exposed to before--not that it would be recognizable anyway, given the fact that vampires reign supreme. She travels with two non-Amish people, one of whom is an anthropology expert who enlightens her on belief systems in other parts of the world, including mythology. I've read quite a few reviews of this book that complain about the religious content, but, as a not very religious person myself, I didn't have a problem with it. I certainly didn't feel like author Laura Bickle was trying to persuade her readers to become Amish, or any other religion. And it was so interesting to watch the character of Katie learn about these other beliefs and compare them to her own, and start to have her own internal theological debates. In fact, I'd say it's one of the things that makes her a strong character--her ability to learn and look at her own beliefs in the light of new information.
And yeah, there are vampires. And they are nasty. But there are moments (not many) when Katie gets a taste of the rumspringa that she'll never really get to have, and that's touching. Even if the world returns to normal, she's seen and learned too much to be able to do a rumspringa with the type of innocence she would have had before the vampires came.
But even with the world upside down and her questioning her beliefs, she grows and matures, and the book ends with at least the hope of a better life coming. Can't ask for much more than that.
