Amazon has become such a giant in online retail that it’s easy to forget sometimes that it used to be all about books. Even its line of hardware started with the Kindle, which was simply a new way to read books.

While Amazon has a whole lot more going for it these days, book sales are still a major component, and the company just announced its list of the top 20 best-selling titles of the year.

“This year’s best seller lists include a lot of familiar authors and characters—over half of the books on the lists are part of a series,” said Sara Nelson, Editorial Director of Books and Kindle. “It’s also exciting to see our January Best Books of the Month pick—and Oprah Book Club pick—The Invention of Wings take the top spot overall. We hope all of these lists will help our customers explore great books this holiday season, whether it’s a gift for a loved one or a treat for themselves.”
