Alex Rosen was having a hard time telling the truth. He sometimes couldn't remember the difference between fact and fiction, fact and fantasy, and fact and just a Big Bold Lie. It's not that he meant not to tell the truth, it just got started in his throat and spilled out of his mouth before he could stop it. His parents came up with a BOLD plan to stop Alex, hoping they will never have to use it. But of course they do, and Alex learns a lesson about truth that sticks with him the rest of his life.
