Clifford Island. When Willow Stone finds these words written on the floor of her deceased son's bedroom, she's perplexed. She's never heard of it before. Determined to find answers, Willow sets out for the mysterious island 200 miles from her home. After a few days on Clifford, Willow realizes: this place is not normal. Everyone seems to be stuck in a particular day in 1994: they wear outdated clothing, avoid modern technology, and, perhaps most mystifyingly, watch the OJ Simpson car chase every evening. When she asks questions, people are evasive, but she learns one thing: close your curtains at night. Five weeks after Willow arrives on the island, she disappears. Willow's brother Harper comes to Clifford searching for his sister, and when he learns the truth-that this island is far more sinister than anyone could have imagined-he is determined to blow the whole thing open.
