After spending six weeks on our hardcover fiction chart, Anita Shreve's Sea of Glass makes an impressive debut at #4 on this week's trade paperback list. Little, Brown reports 470,000 copies of the Back Bay Books edition after three trips to press. Shreve's many fans don't have long to wait for her next opus: All He Ever Wanted is due April 15—not a taxing read, we trust.
