A peaceful alternative mystical land called Ledremain is attacked by creatures known as 'Gloamins'. Two young girls escape to earth and hide in a magical attic for their protection. A young girl called Freya, who lives downstairs, discovers their secret. The three teenage girls and their magical sketch book travel through a painting on the attic wall. They embark on an adventure to rescue a group of children. They must also prevent the Gloamins from finding a key. This key would unlock the attic window and allow the Gloamins to gain direct access to Earth.
In Book Two, Freya, Jalay, Sithe and Lyoneth travel through another attic painting in search of the second key. Here they visit a snow covered land, where they encounter the ferocious Kilcons and the mind controlling Snow Gatherers.
