On Wednesdays, the Pacific Northwest Booksellers Association Bestseller list is published. Every week, we love to see what has been most popular in independent bookstores around our region. As we peruse the list, we ponder patterns. Then we present this weekly feature: Thursday Themes.

Look at all the animals in titles this week! It’s a veritable menagerie.
