If you haven't read the book, you'll almost certainly have seen Peter Jackson's epic three-part movie adaptation of it. Incredible though the films are, there's inevitably a lot missing from them and it's well worth persevering with the book's slowish start to follow the journey of Frodo and friends more closely. If you're not familiar with the story, The Lord of the Rings tells the story of a hobbit, Frodo, who must undertake a dangerous mission to the dark land of Mordor to destroy a powerful ring – a weapon that absolutely corrupts those who come under its power. As you'll soon find out, that's a highly simplified plot summary!
Reading the book, you'll be hard-pressed not to gain a deep admiration for the detail and thought Tolkien put into creating his imaginary world; languages, detailed family trees, maps, rich histories and backstories – all add to the sense of realism one feels when absorbed in Tolkien's work. You'll also spot some of Tolkien's influences, such as Nordic mythology and the Anglo-Saxon poem Beowulf (read this poem alongside Tolkien and you'll notice where his inspiration for the Golden Hall came from).
