The title of this book, 'From Zero to Hero' is interesting from two points of view: a) many students, proficient speakers of English, begin their higher education studies with no knowledge of phonetics and phonology, but by going through this subject have every chance of becoming 'heroes', to teach others, in turn, its secrets; b) the material included in the book covers almost all the basic notions of this branches of linguistics, considered by Stephen Ullmann (1957) the foundation stone of a any language. What seemed to me the greatest gain of the book are the exercises presented at the end of each chapter, and the tests at the end of the book. Through their variety, they encourage students to verify and consolidate the theoretical notions acquired.
