Twelve-year-old Gracie is enjoying summer up north with her brother and cousins when the beloved bald eagles who live on the neighboring property go missing. They investigate and soon discover there's more at stake than the missing birds. The sleepy waterfront town full of untouched natural places may be developed for commercial purposes, disrupting the idyllic peace. It all depends on their frightening neighbor, Hunter Bruce, and whether he will sell the coveted piece of land to the township. Gracie and the others decide they must convince him not to before it's too late.
