Babel No More is a scientific book -- not in the sense that it's laden with charts and figures, and not because the action takes place in laboratories, but because it attempts to provide reliable information about language superlearners, that is, information that's not self-reported or anecdotal, but that can be verified, compared, and synthesized with other knowledge. And that's never been done before, not on this topic, of people who can speak a lot of languages and who have an easier time than others learning them.
