When Sally and Joey embark on a hike in the Red Hill Valley with their science teacher, Mr. Z, they never expect to be shrunken in size by a wayward cascati spell. Who knew the mysterious nature lovers depended on the falls for their life source and magic?

Beautiful, adventurous Xiomara, daughter of elder Kuku, eagerly awaits for her twin sister, Xhalla to give birth. When Albion Falls runs dry, the twins need to attempt the trek to their estranged brethren at Felker's Falls, to ensure life source for Xhalla's unborn child. Could elder Zanta, the mythical leader of the Felkrati, hold the key to returning their new human allies to giant size?

Now, human and cascati must band together to overcome the perils of the woods and the uncertainty of being linked on a life or death quest with a dangerously fascinating new species.
