Thirteen-year-old Jay survived a shark attack. He has a big scar on his body, and he doesn’t remember exactly what happened. Sadly, his estranged mum didn’t survive the horrific accident, and Jay and his dad have moved to the west coast of Ireland, where he surfs and keeps his past a secret. He’s not allowed a phone, and they don’t have the internet at home. But when he and his friend Jess do some research for her family’s surfing school, he discovers something that makes him sure his dad has been lying. Suddenly Jay doesn’t recognise the dad he’s trusted all his life. So what really happened on the terrible day he can’t remember?
