Every night at exactly 11:11 PM, seventeen-year-old Elia receives a message from an unknown number. At first, the messages seem harmless. They predict little things that haven't happened yet—an unexpected quiz, a forgotten umbrella, a conversation with a friend. Then one night, the message changes. **DON'T TRUST THE BOY WHO WILL SIT BESIDE YOU TOMORROW.** The next morning, Elia walks into class and finds a new student sitting in the empty seat beside hers. His name is Noah. He knows things he shouldn't. He notices things no one else does. And somehow, the mysterious messages seem to know him too. When the unknown sender claims to be Elia herself—one year in the future—Elia is forced to question everything she believes. Who is really sending the messages? Why does the future seem desperate to warn her about Noah? And if Elia changes what is supposed to happen, will she save her future—or destroy it? Some messages are warnings. Some are lies. And some are never meant to be received.
