But this special world is under threat: Alfred's dad is working on a project to dig a giant tunnel through the landscape for a motorway. As he joins Saga in the community protests against the plan, Alfred draws ever closer to the strange world of the faerie creatures, following a thread that seems to be leading him deep into secrets from his family's past.
