The Battle of Lynher Mill (The Lynher Mill Chronicles) (Volume 3)

When loyalties are twisted, and terrors are fed, even the most peaceful of creatures will commit unthinkable acts in the name of vengeance... and who will be left to stop them? They face each other across the expanse of moorland that covers the west of Cornwall; a reluctant king on one side, a misled lord on the other. Both desperate to secure the support of a third faction, The Foresters, they are forced into using their oldest and most powerful weapon: the elements themselves. But their gifts have become stale and unwieldy in their hands, and what once came easily, and naturally, is now a hard lesson to learn and an impossible force to control. As the elementals wreak havoc, and bring darkness and death thundering down upon each other, a frantic mother armed only with the truth will stop at nothing to find her child and bring him home. But in the end it's the truth itself that could kill her.
