Here is a link to the best books list from Publisher's Weekly.

Picture books: http://best-books.publishersweekly.com/pw/best-books/2016/picture-books#book/book-14

From here, you can link to the middle grade and YA lists as well. Happy to report that I have read. Out of these outstanding books already. But the ones I have missed make for a good start to a TBR stack, too.
