I think this is a super fun middle-grade story. It feels like a mix of Nancy Drew and The Ghostbusters, and the characters were all enjoyable, helping to enhance the plot with their personalities alone. I also found the humor throughout to add a nice effect to the overall plotline, allowing the mystery to not be too spooky. I really love the family connection that runs through this story, as well. There are so many different ways in which this book looks at family, both by blood relations and friendship connections, showing readers that you can choose your family. I am looking forward to recommending this book in the future!
