Banned Book Week was launched in the US in 1982 by the American Library Association (ALA) to encourage libraries and bookshops to hold events celebrating the right to read. This year, it’s mostly virtual.

Here are the ALA’s top 20 most-challenged books of the decade:

1. The Absolutely True Diary of a Part-Time Indian by Sherman Alexie
2. Captain Underpants (series) by Dav Pilkey
3. Thirteen Reasons Why by Jay Asher
4. Looking for Alaska by John Green
5. George by Alex Gino
6. And Tango Makes Three by Justin Richardson and Peter Parnell
7. Drama by Raina Telgemeier
8. Fifty Shades of Grey by EL James
9. Internet Girls (series) by Lauren Myracle
10. The Bluest Eye by Toni Morrison
11. The Kite Runner by Khaled Hosseini
12. Hunger Games by Suzanne Collins
13. I Am Jazz by Jazz Jennings and Jessica Herthel
14. The Perks of Being a Wallflower by Stephen Chbosky
15. To Kill a Mockingbird by Harper Lee
16. Bone (series) by Jeff Smith
17. The Glass Castle by Jeannette Walls
18. Two Boys Kissing by David Levithan
19. A Day in the Life of Marlon Bundo by Jill Twiss

Amazing to think, isn’t it, that books that have long been considered classics, like To Kill a Mockingbird by Harper Lee and The Bluest Eye by Toni Morrison, are banned in some places. This list reminds us just how important it is to say freely and joyously whatever we feel called to say. Write on!
