Where has Faith's dad gone? Why has he left his family living in an old house perched on a crumbling cliff top? A crack has appeared in the cliff and Faith watches anxiously as it gets bigger and bigger each day. Her brother is obsessed with the sea ghosts he claims live in the basement, and when he disappears as well, Faith starts to believe in the ghosts too. Can she find her brother and bring her father back before everything she cares about falls into the pitiless sea below?
