Josh and Maddy return to Calgary after a visit to their grandmother's house in Saanich. As they travel on the ferry from Vancouver Island, Maddy purchases a ring. She soon discovers that the ring is no ordinary ring - it is magical! Unfortunately, a character named Gronvald wants the ring. Josh and Maddy meet Aleena, who offers to help keep the ring from Granvald. She takes the two children through a veil of magic to a world of otter-people that co-exists with the human world. Josh and Maddy soon discover that they cannot trust Aleena, who covets the ring. The otter-people insist that the ring be returned to the giant of Castle Mountain so it can no longer damage the veil between the two worlds. Josh and Maddy must return the ring to the giant, and then try to find their way home.
