English Grammar for Students of Spanish by Emily Spinelli

I found this grammar book practically useless. It is designed to supplement Spanish textbooks and fill in any gaps in the student's English grammar. Unfortunately, it only covers the most basic topics of grammar. Often its explanations for how to identify grammatical elements in Spanish are only "the same as in English." I would have preferred to buy a Spanish grammar rather than dallying around with this waste of time, money, and paper.
