Books in the Tales from Kinloch series

It's December 1967, and the town of Kinloch is cut off by heavy snow. With all roads closed, the only way to feed and water the townsfolk is for the fishing fleet to sail to Girvan for much needed supplies. The crew of the Girl Maggie embark upon a trip like no other, encountering ghostly Vikings, gigantic crustaceans and a helpful seagull.
