In 2003, the Tolkien Society started celebrating Tolkien Reading Day. "The 25th of March was chosen as the date on which the Ring was destroyed, completing Frodo’s quest and vanquishing Sauron." You can read the Society's post on 2020 here. If you are going social with how you are celebrating use the tag: #readtolkienathome2020 and many continue to use #TolkienReadingDay.
People are encouraged to read any fiction or non-fiction Tolkien related work, but a theme is offered for those who find it hard to choose.
This year's theme is "Nature and Industry."
One of the suggested readings is Leaf by Niggle. This short work by Tolkien ranks at the top of my list along with The Hobbit, LoTR, and anything related to Turin.
I happen to have read it last week, so I'm looking for something else to dive into tonight.
Another recommendation is LoTR's Scouring of the Shire. I decided to read Homeward Bound and Scouring of the Shire from The History of Middle Earth, Volume IX, Sauron Defeated.
Enjoy and have a great read!
