THE BURIED TREASURE OF MT. GRETNA tells how a treasure, stolen from a survivor of the Titanic and dropped by an escaping thief into young Minnie's lap, affects her family-and far beyond. Minnie buries the treasure behind a stone-covered spring in Mt. Gretna Park and boards the park's ill-fated train. Eighty years later, Susan finds the treasure in the now-abandoned park. She is struggling to reconcile with her hateful stepbrother as she tries to solve the mystery of the treasure's elusive past. Who buried it behind the spring? What could absent-minded old Nana know, and will Susan discover the hidden truth behind the treasure-its true owner-before the detestable Mr. Haverstock claims the prize?
