"Languages make us human. The ability to communicate and be understood through songs, art, words, inscriptions, or even gestures is essential because we, as a species, cannot live in isolation. And each one of these languages has its own journey. Early humans leaving messages on cave walls; three men on a raft stumbling upon a language they weren't looking for; a secret language that evolved to hide a people; the world's only undeciphered language that is 4000 years old. The stories in this book take you from the northeastern-most tip of our country to the forests in central India, from indigenous languages that are thousands of years old to those that have developed recently." -- Amazon.com
