From the description:
Deep in the wild countryside is a rocky cove, with cliffs on both sides surrounding a fast-running stream down a steep valley. At high tide there are just unforgiving rocks, but at low tide a large beach is revealed giving access to some caves and small islands. A number of giant’s boats have been wrecked here over the years due to the treacherous coastline and one of these boats is upturned and mostly intact: this is the home and workplace of Rose Buckthorne, Master Blacksmith of Giant’s Cove.
Rose, with her apprentice Rowan and assistant Erin, scavenge the cove for materials to make exclusive weapons and armour. Limpet shells make strong shields, razor clams are formidable weapons, fishing nets provide an incredibly strong but light rope, and muscle shells can be used as body armour.
