This is the sequel to Hex Hall. In order to properly enjoy this book, I highly encourage you to read it first. This is not a trilogy to read out of order. 
 In some ways I enjoyed this more than the first one, and in others a bit less. To start, I liked the writing better. I didn't feel the topics and style were geared towards teens only. While a young adult book, this one did not rub me in the annoying way the first book did at times. 
 However this book did not really grab and easily hold my attention either. Easily put aside and forgotten. Especially the middle of the book. I struggled to get through it. Nick and Daisy do not help. They bored me. The first book in the series threw some unexpected twists throughout the book. This one not so much. That is not to say it was bad or I didn't enjoy it. Just that it didn't jump out at me. 
 In this book, Sophie is sent off to spend the summer with her father. Lucky for her, Cal and Jenni get to go with her. She has a lot to learn about her heritage. From there, things go several directions at once and none of them play out in a way that drove my curiosity. 
 I am liking Cal's character more and more. I think he is my favorite character in this series. He may seem like the quiet, healing gardener, but it is easy to tell there is more to him. I have mixed thoughts on Sophie's dad. He is too career focused but I think he has a good heart. The other new characters were disappointing. 
 Now while much of the book was just so-so, the ending has me really wondering what is to come next. One cannot read this and just stop so kuddos for an amazing cliffhanger ending! 
 Overall 3.5 stars
