The Third German Shepherd who Howled at the Moon

When their troops go to Lynx Lake, siblings, Adam and Caithlin, along with their friend Ella, accidentally don’t follow the rules. They find themselves stuck in a dilemma they don’t know how to get out of. Last fall, the siblings found a magic wolf tooth on a family camping trip. Can the wolf tooth help the kids, or will it cause the catastrophes it did in the past? Will their German Shepherd Dogs somehow save them?
