Spanish will be my third language and this time I'm teaching myself. This is a good book to have as one of many tools in your arsenal. Positives: the book is a nice alternatively to a typical grammar book. It presents a lot of good, useful vocabulary that continues throughout. I've actually used some of the vocabulary I learned in this book. It definitely progresses from easy, present tense in Part I to more difficult past tense in Part II and additional tense usage in Part III. I found Part II on the history of Mexico most interesting and Part II the literature was descent as well. I like that there are questions after each passage with answers in the back. These exercises gave me an opportunity to write and reinforce the vocabulary I was learning. Negatives: Part I content is a bit remedial, but you have to start somewhere so kind of as expected. As for the Q&A, I found some mistakes throughout the book and sometimes there were two-part questions, but only one answer. The verb tenses get more difficult as you advance your way through the book, which I liked, but I wish there was some kind of explanation...perhaps I am asking for too much. In any event, I would definitely look for a similar book and this book has inspired me to check out the literature in Part III and continue to learn through reading!
