In particular, I'm looking for English texts which try to give some sense of the vast diversity of human languages through examples of unusual linguistic features exhibited in only one or in a small number of languages. A kind of compendium of linguistic exotica, if you will. A sort of sensationalized popular introduction to linguistics, with the aim of getting a young person interested in the field.
This genre seems to exist in most fields. For instance, if you wanted to get someone interested in astronomy you wouldn't give them a physics textbook to begin with, instead you'd get them started with a book on black holes and quasars and relativity and other juicy exotic junk like that.
Is there something similar in the field of linguistics? It would be fair to say that I'm looking for a gateway drug to the field.
