"It all began when we found the bones." This is the start of Erosion, a gothic novel set on the English coast, in 1987, the year of the Great Storm. Violent weather is but one of the problems a group of friends face when they discover an ancient grave inside a crumbling cliff and decide to unearth a skull. Supernatural mystery intertwines with the problems of human relationships, of earning money, of following dreams. Alison wants to spend a glorious summer writing her novel, Asher wants to wow audiences with his comedy routines, Zoe wants to make a living as an artist, Jo wants to make the world a better place and Baz just wants to help his friends succeed, but the events that happen change all their plans. Death and destruction test the bonds of friendship, yet moments of beauty entwine with scenes of horror as a magical summer becomes an autumn of devastation.
