The Complete Idiot's Guide to Spanish Verbs

In the first and the second chapters, the author has done a wonderful job in providing readers a whole picture of the Spanish verbs, including how all the tenses are formed and how the verbs are to be systematically and properly conjugated. The sketch for spelling-changing verbs on page 21 and the sketch for stem-changing verbs on page 25 are unique and I have never seen the better presentation in other books. Appendixes D, E, and F also provide a more extensive list of spelling and stem changing verbs than most of other books. I have many Spanish grammar books about the Spanish verbs, but I found this is the most useful for me. However, the book needs to provide more examples, and to use more examples in a form of a complete sentence instead of a simple phrase.
