For the second quarter in a row, Stephenie Meyer‘s Twilight series has commanded the top four spots on the USA Today‘s Bestselling Books list.

Earlier this year, we noted that one in every seven books sold in the previous quarter was a Meyer book–comprising 16 percent of all books sold in the first months of 2009. In case the four bestselling titles weren’t enough for you, look for another movie book in October.

Check it out: “‘New Moon: The Complete Illustrated Movie Companion” is already available for pre-order (even though the cover art has not been released). For those of you who haven’t seen the Twilight Companion, it is filled with high-quality images and behind-the-scenes information.” (Via Publishers Lunch)
