A story of first love and second chances from the bestselling author of Love Rules The sleepwalker. By day, Petra Flint is a talented jeweller working in a lively London studio. By night, she sleepwalks. She has 40 carats of the world's rarest gemstone under her mattress but it's the skeletons in her closet that make it difficult for her to rest. The insomniac. At one time a promising song-writer, Arlo Savidge now teaches music at a boys' boarding school in North Yorkshire. He assumes he's happy with his isolated lifestyle. But, like Petra, ghosts from his past disturb his sleep. Putting the past to bed. Petra and Arlo loved each other from afar during their schooldays. Now, seventeen years later, in a tiny sweetshop one rainy day, they stand before each other once more. Could this be their second chance?
