Our middle-aged narrator returns to a farm at the end of the lane he grew up on, and memories awaken inside him as he looks at the pond, of strange happenings when he was seven. His new friend Lettie, who had led him on a magical adventure where he had allowed a terrifying creature into the world, which attacked him and his family in ways he could hardly understand. Terrifying, dangerous, magical experiences and encounters that he has forgotten – and that he will forget again. But what happened to Lettie?
I love the mixture of the mundane and the magical. And you get a sense just from the title here that there isn’t just an ordinary sea at the end of the lane. Here Gaiman masterfully pulls magic into everyday life, and creates complex characters with fairytale encounters. Of his books like this (The Graveyard Book, Coraline, I would say) this was my favourite!
