Any REALLY good books to improve essays?

<p>I am an undergraduate English major with organizational and grammar problems. I have also been told that I can be "too general" in my essays (thought I think I have combatted that). I just want a books that will give me examples and opportunities to practice.</p>

<p>I have been told that I can try to condense by ideas. I would really like a book that may have helped you (Especially English Literature graduates!).</p>
