I would recommend any of the following:

Wardhuagh, Ronald. Understanding English Grammar: A Linguistic Approach.
Blackwell, 1995.
Lobeck, Anne. Discovering Grammar: An Introduction to English Sentence
Structure. Oxford U. Press, 2000
Kolln, Martha, & Robert Funk. Understanding English Grammar. Allyn &
Bacon, 1998 (although I understand a newer edition is on its way).

These aren't as simple as commercial books you'll find (they are
intended as college textbooks), but they cover crucial information that
traditional grammar books (the kind used in  K-12 schools) miss, and
they have a more accurate and up-to-date view of language than
traditional books. These titles and others are widely used in college
grammar courses.

For a traditional grammar book aimed at college with relatively complete
coverage of the usual issues traditional grammar targets, see Donald W.
Emery et al., English Fundamentals, Allyn & Bacon 1998 (11th edition). I
strongly recommend that you consult one of the above books in addition
to Emery (or similar books).

I commend you on wanting to study grammar! Feel free to write to the
list with questions!
