Ghosts of the Fallen. Southern Magic, #4

After the terrible events of Halloween 2018, Gideon and Jordy have moved their growing family to Gideon's ranch in Wyoming where they settle into a perfectly routine life, or as perfectly routine as one can get for two immortals, an adopted mage, a goblin butler and a teleporting, fire-breathing dog. Elsewhere, a string of brutal murders begins to point to a supernatural assassin that leaves few, if any, clues operating in the Program's jurisdiction.
When the latest killing strikes too close to home, Gideon, Jordy, and their family are drawn into an adventure with world altering ramifications.
