The secret is a colony of beavers, a species that is craved for their fur pelts, but vilified for what humans consider to be the destruction of their land. No beaver has been spotted in Scotland or England for over five hundred years, until the young beaver, Dunwattle, is sighted! Dunwattle’s flight is driven by the presence of a ghostly figure, a figure of a mysterious young girl who is almost one thousand years old. And now Dunwattle is destined to be destroyed for revealing the hidden colony, but his best friend Locksley is determined to save him. Will their ancient beaver colony survive?
