Perfect studyguide for the serious language learner!
This guide was very well written, with lots of explanations and exercises and answer keys.  It has been a pleasure learning Spanish with this Destinos set.  I recommend it very, very highly.
This is not a guitar instructional book. This is an anthology or compilation of latin songs.  It's a songbook with chords. If you are looking for a guitar method, try others books like guitar methods by Wolf Marshall, Carcassi method, Noad's First Book for guitar or any Mel Bay complete method for guitar, etc.
