1. The Hobbit and The Lord of the Rings: This is the natural starting point. The two works form a coherent narrative arc, with *The Hobbit* serving as a prequel to *The Lord of the Rings*.
2. The Silmarillion: This book is a collection of Tolkien's myths and legends about the creation of Middle-earth, the First Age, and the rise and fall of the Elves. It's dense and complex, but it provides essential background for understanding the world of *The Hobbit* and *The Lord of the Rings*.
3. The Adventures of Tom Bombadil: This collection of poems and stories offers a glimpse into the lighter side of Tolkien's imagination, featuring a whimsical character and an emphasis on nature.
4. Unfinished Tales of Númenor and Middle-earth: This book contains fragments of stories, essays, and notes that Tolkien never completed. It offers valuable insights into his creative process and the history of Middle-earth, but it's not a standalone narrative.
5. The Children of Húrin: This epic tragedy, originally written in the 1920s, tells the story of a doomed family during the First Age of Middle-earth. It's a powerful and moving tale that stands alone, but it builds upon the mythology established in *The Silmarillion*.
6. The History of Middle-earth: This series of twelve volumes comprises Tolkien's notes, drafts, and essays relating to the creation of his mythology and stories. It's a deep dive into Tolkien's process but intended for dedicated fans and scholars.
Note:
* Reading order is flexible. The above list is just a suggestion; you can tailor it to your interests and reading preferences.
* "The Silmarillion" is challenging. This book can be demanding for first-time readers, and it's generally recommended to read it after *The Lord of the Rings*.
* Consider your preference for "mythology" vs. "stories." *The Silmarillion* is primarily mythology, while *The Children of Húrin* is a more traditional story.
Enjoy your journey through Tolkien's world!
