Elly's Adventures - Misty Mountains - Catherine Harms

When Elly and her friends, Sara and Karen, set off for a camping adventure at Misty Mountain, they expected two weeks of swimming, hiking and exploring. But from the moment they arrive, Elly senses there is something unusual about Misty Mountain.
Strange lights appear in the night, a mysterious park ranger, figures appear and disappear, and Elly begins hearing a voice calling her towards the mountain.
Drawn deeper into its secrets, Elly discovers that something magical lies hidden beneath the rocky slopes—and a dangerous force is searching for it.
With time running out, Elly must trust her intuition and find the courage to face another magical adventure filled with friendship, mystery and danger, are closer than she ever imagined.
