I bought this book after having it recommened by my Spanish teacher. I used it regularly within my Spanish classes and now that my Spanish is more fluent still refer to it as a reference to help me occassionally.
It is really helpful as you can see side by side in each page how grammar apply in English & in Spanish. Perfect for those that try to make English rules adapted to Spanish (they are different).
