Amazon is known for its annual best book lists, but when the e-commerce giant dropped a new book compilation this week, we were pretty surprised. After all, it's only June.

It turns out that there have already been so many standout novels and non-fiction books that Amazon came out with a "best of" list for 2017 so far. Every book on the list was released between January and June of this year and was hand-selected by Amazon Books Editors.

The title of top book of the year (so far) was given to The Ministry of Utmost Happiness: A Novel by Arundhati Roy.

“Our top pick this year, The Ministry of Utmost Happiness is a sweeping yet intimate story, one that packs heartbreak, humor, love and acceptance—and a memorable cast of characters—into a novel that will stick with readers for a very long time," said Sarah Harrison Smith, Amazon editorial director of print and Kindle books.
