After going through a tragedy, Katie has recently relocated to Columbia, Minnesota and taken a job as a high school math teacher. While exploring some local trails with her black lab, Maverick, she discovers a body and is forced into the role of amateur sleuth. Katie is a lovable, relatable character, and the supporting cast--including the sweet and hilarious Maverick--really makes these books a joy. If you're a fan of math, codes, or riddles, this series will be a particular treat for you! A former cryptologist and current math teacher, Katie is an expert on these topics, and Seifert weaves these elements through the story. I've read other books in Seifert's series and really enjoyed reading the first one to see how Katie's story began. If you're looking for a smart, charming cozies, check these out!
