Kelley Armstrong is one of my favorite authors and she is known for her “Otherworld” series. Hidden is book for the fan of the series as it a way to say goodbye to some characters. However, if you have never read an Otherworld novella then is a nice treat and fun to read. The story centers around Clay and Elena and their twins, Kate and Logan as they are in wilderness celebrating the Christmas holiday. The special thing about this family is they are werewolves [the twins are too young to know this] and Clay is the Alpha and Elena is his mate. Wherever these two go, trouble soon follows and personal time is hard to come by and this trip is no exception. Enjoying time with their family, Clay and Elena are thrown into mystery and mayhem when a mutt enters their family circle. Trying to keep their identities secret and protecting the family the couple go an investigation which leads them to mysterious deaths of some local citizens. This is a good quick read.
