On page 11 a short passage entitled "The Keys to Recovery" explains what the book is about. "Mental illness . . . locks you in," it says, preventing you from doing things and going places and achieving goals. "Antipsychotic medications are the keys" that can unlock the door. Of the many such medications available, you don't know which of these "keys" may unlock the door for you. "Don't give up if the first medication doesn't work," the book says. "Don't keep taking the same medication for years if it doesn't work. There are other medications to try." But the book also cautions later that antipsychotic medications must be taken regularly, in appropriate doses, for a period of time before they begin to work.
