This is a different book for the series as it is more fantasy/adventure with some interesting mythology thrown in. It has some of the same tropes: siblings, solving a problem without an adult, spooky things that turn out to not be so spooky, and an ending that will make you think. I just didn't connect with it like I wanted ... still had a good time and the story was fast paced as they encounter one creature/ obstacle after another. 2.5 stars
