5 stars

Another fantastic, amazing, superb Hilda adventure. I loved this book. It was so good. I was immediately hooked by the concept. As with the other books, I loved the story, I loved the characters. Everything was just perfect.

This one does have quite the cliffhanger at the end. I am going to be freaking out about it until the next book comes out. Luckily, I have the Netflix show to keep me sane for a little longer. 

Just amazing.
