"Take this book with you wherever you go, and make sure that you do not leave the boundaries of Hillsborough. Remember, no one can read the book, including you both. When you see Jacob, give this book to him. Do you understand?"

"That's all. Take this book with you and leave. Tell no one about this," Adam reminded them before giving a dismissive wave.
