Jessie is drawn to the sea off Brighton Beach.
Having newly joined a local sea swimming club, he has at last found a way to clear his head from the nightmares that have terrorised him since birth. But what Jesse doesn't see, what lies beneath him as he swims around the Brighton Palace Pier each morning, is a mystery from the past that will once again come to the surface with deadly consequences.
Lilly Baker dies during a terrible storm that ravaged the old Brighton Chair Pier and sent it crashing into a raging sea. But Lilly's need for revenge was too strong to die with her and has haunted the Brighton Sea Swimming Club for nearly two hundred years.
Lilly won't rest until everyone pays the ultimate price for her loss. Jesse can't rest until the terrible nightmares stop haunting him.
