“Perhaps there will be two or three readers out there who manage to finish the first chapter of this terrific debut and put it down for more than an hour. But they’ll be back. And they’ll devour Need to Know like the rest of us, skipping lunch, losing sleep, turning pages until the end, where we’re all left waiting for more.”

—John Grisham
