Finn is haunted by terrifying dreams where a huge wave threatens to engulf her in watery darkness. They have been worse since she arrived at the Cornish cottage. Then she discovers the strange curse that was laid upon the cottage years ago, and she's sure vengeful Griffiths has something to do with it. She's seen him, endlessly tying and retying a length of rope, creating the knots that — superstition has it — can conjure storms. Finn knows that she's in mortal danger if she can't find a way to break the curse... This is a superbly spine-chilling teen thriller from the award-winning author of Witch Child.
