This trilogy was not intended to be one. J.R.R. Tolkien spent twelve years writing The Lord of the Rings, and he intended them to be both a sequel to The Hobbit and the second of a two volume set with The Silmarillion. Instead, his publisher insisted on breaking The Lord of the Rings into three books. I’d say it was a decent strategy, as The Lord of the Rings has become the third highest selling book of all time.
Even more importantly for me personally, The Lord of the Rings launched a literary genre, high fantasy fiction, that I have come to love. With these books, Tolkien established a framework within which thousands of other books have been written. I have enjoyed quite a few of them, more than any other genre I have read by a wide margin.
The Lord of the Rings was not just an amazing story, it was groundbreaking and revolutionary, and that’s why I wish I’d written it.
