Book excerpt: This is a book about three men who started out as strangers but soon found themselves to be friends. The 3 Amigos - as I like to call them - each have a passionate and abiding love for all spirits agave - but especially tequila. In fact, they are lovers of virtually everything Méxicano - from the drinks, to the food, the art, the people, the music and the architecture. Yet - they are well-entrenched in their careers and the neighborhoods in which they live. With this much duality - something is bound to give - and a series of unrelated (?) happenstances has put their resolves to the test.
